• Minimum vs Minimal vertex covers

  - by panicked

  I am studying for an exam and one of the sample questions is as follows: Vertex cover: a vertex cover in a graph is a set of vertices such that each edge has at least one of its two end points in this set. Minimum vertex cover: a MINIMUM vertex cover in a graph is a vertex cover that has the smallest number of vertices among all possible vertex covers. Minimal vertex cover a MINIMAL vertex cover in a graph is a vertex cover that does not contain another vertex cover (deleting any vertex from the set would create a set of vertices that is not a vertex cover) Question: A minimal vertex cover isn't always a minimum vertex cover. Demonstrate this with a simple example. Can anyone get their head around this? I am failing to see the distinction between the two. More importantly, I'm having a hard time visualizing it. I seriously hope he's not gonna ask odd questions like this one on the exam!

• iphone: custom UITableViewCell taller than the default cell view.

  - by Luc

  Hello, I'm creating an application that consists of a ListView with 5 rows: - 1st one containing a graph - 2nd to 5th rows containing some data with the same formatting. I have created 2 classes: GraphCustomViewCell and DataCustomViewCell. Depending upon the position of the cell I load the correct CustomCell with: NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"GraphCustomViewCell" owner:nil options:nil]; for(id currentObject in topLevelObjects) { if([currentObject isKindOfClass:[GraphCustomViewCell class]]) { cell = (GraphCustomViewCell *)currentObject; break; } } That works fine except that the first row, the one corresponding to the graph, is bigger (in height) that the 4 other rows, and as a results it hides the 3 first other rows. Is there any option in the table view that enables the custom cell to expand the default cells ? I'd like that the 5 rows (graph + 4 data rows) to fit the entire screen (480 - tabbar's height). Thanks a lot for your help. Regards, Luc

• MATLAB fill area between lines

  - by dustynrobots

  I'm trying to do something similar to what's outlined in this post: MATLAB, Filling in the area between two sets of data, lines in one figure but running into a roadblock. I'm trying to shade the area of a graph that represents the mean +/- standard deviation. The variable definitions are a bit complicated but it boils down to this code, and when plotted without shading, I get the screenshot below: x = linspace(0, 100, 101)'; mean = torqueRnormMean(:,1); meanPlusSTD = torqueRnormMean(:,1) + torqueRnormStd(:,1); meanMinusSTD = torqueRnormMean(:,1) - torqueRnormStd(:,1); plot(x, mean, 'k', 'LineWidth', 2) plot(x, meanPlusSTD, 'k--') plot(x, meanMinusSTD, 'k--') But when I try to implement shading just on the lower half of the graph (between mean and meanMinusSTD) by adding the code below, I get a plot that looks like this: fill( [x fliplr(x)], [mean fliplr(meanMinusSTD)], 'y', 'LineStyle','--'); It's obviously not shading the correct area of the graph, and new near-horizontal lines are being created close to 0 that are messing with the shading. Any thoughts? I'm stumped.

• Pylons and Facebook

  - by Nayan Jain

  The following is my oauth template top.location.href='https://graph.facebook.com/oauth/authorize?client_id=${config['facebook.appid']}&redirect_uri=${config['facebook.callbackurl']}&display=page&scope=publish_stream'; Click here to authorize this application When I hit the page I am prompted to login (desired), upon login I am redirected in a loop between a permissions page and an app page. My controller looks like: class RootController(BaseController): def __before__(self): tmpl_context.user = None if request.params.has_key('session'): access_token = simplejson.loads(request.params['session'])['access_token'] graph = facebook.GraphAPI(access_token) tmpl_context.user = graph.get_object("me") def index(self): if not tmpl_context.user: return render('/oauth_redirect.mako') return render('/index.mako') I'm guessing my settings are off somewhere, probably with the callback. Not to sure if it is an issue with my code or the python sdk for facebook.

• how to use drawItems() in PyQt?

  - by DSblizzard

  I have these two code fragments in program: class TGraphicsView(QGraphicsView): def __init__(self, parent = None): print("__init__") QGraphicsView.__init__(self, parent) def drawItems(self, Painter, ItemCount, Items, StyleOptions): print("drawItems") Brush = QBrush(Qt.red, Qt.SolidPattern) Painter.setBrush(Brush) Painter.drawEllipse(0, 0, 100, 100) ...

• How can I use gnuplot to plot data that is in an un-friendly format?

  - by Zack

  I need to graph some data that is not exactly in the most friendly format, most examples or usage puts things in a nice column/table that is very easy to parse and graph. However I have the following format (and am a bit stuck as to how to tackle this): DATE1 label_1 xx yy DATE1 label_2 xx yy DATE1 label_3 xx yy DATE2 label_2 xx yy DATE2 label_3 xx yy DATE3 label_1 xx yy DATE3 label_2 xx yy DATE3 label_3 xx yy DATE4 label_2 xx yy DATE4 label_3 xx yy ...continues *I've added the extra space between the dates for readability. **Note: under DATE2,DATE4 label_1 is missing, i.e. the data file may have labels that come and go and should represent a discontinuity in the graph. I'd like to have the X-axis use the DATEX for the labels, and then create two lines for each label (xx and yy respectively). Does anyone have any suggestions on the best way to tackle this problem?

• jqTouch - why does the transition has no animation?

  - by teepusink

  Hi, I'm using jqTouch. Trying to figure out why when the scene / div change, it just change abruptly without the slide animation? Here is the setting that I have now: var jQT = new $.jQTouch({ slideSelector: '.link', useAnimations: true }); Again the scene change works just fine, just that I don't see the slide animation. What am I missing? Thanks, Tee

• OpenGL ES functions not accepting values originating outside of it's view

  - by Josh Elsasser

  I've been unable to figure this out on my own. I currently have an Open GLES setup where a view controller both updates a game world (with a dt), fetches the data I need to render, passes it off to an EAGLView through two structures (built of Apple's ES1Renderer), and draws the scene. Whenever a value originates outside of the Open GL view, it can't be used to either translate objects using glTranslatef, or set up the scene using glOrthof. If I assign a new value to something, it will work - even if it is the exact same number. The two structures I have each contain a variety of floating-point numbers and booleans, along with two arrays. I can log the values from within my renderer - they make it there - but I receive errors from OpenGL if I try to do anything with them. No crashes result, but the glOrthof call doesn't work if I don't set the camera values to anything different. Code used to set up scene: [EAGLContext setCurrentContext:context]; glBindFramebufferOES(GL_FRAMEBUFFER_OES, viewFramebuffer); //clears the color buffer bit glClear(GL_COLOR_BUFFER_BIT); glMatrixMode(GL_PROJECTION); //sets up the scene w/ ortho projection glViewport(0, 0, 320, 480); glLoadIdentity(); glOrthof(320, 0, dynamicData.cam_x2, dynamicData.cam_x1, 1.0, -1.0); glClearColor(1.0, 1.0, 1.0, 1.0); /*error checking code here*/ "dynamicData" (which is replaced every frame) is created within my game simulation. From within my controller, I call a method (w/in my simulation) that returns it, and pass the result on to the EAGLView, which passes it on to the renderer. I haven't been able to come up with a better solution for this - suggestions in this regard would be greatly appreciated as well. Also, this function doesn't work as well (values originate in the same place): glTranslatef(dynamicData.ship_x, dynamicData.ship_y, 0.0); Thanks in advance. Additional Definitions: Structure (declared in a separate header): typedef struct { float ship_x, ship_y; float cam_x1, cam_x2; } dynamicRenderData; Render data getter (and builder) (every frame) - (dynamicData)getDynRenderData { //d_rd is an ivar, zeroed on initialization d_rd.ship_x = mainShip.position.x; d_rd.ship_y = mainShip.position.y; d_rd.cam_x1 = d_rd.ship_x - 30.0f; d_rd.cam_x2 = d_rd.cam_x1 + 480.0f; return d_rd; } Zeroed at start. (d_rd.ship_x = 0;, etc…) Setting up the view. Prototype (GLView): - (void)draw: (dynamicRenderData)dynamicData Prototype (Renderer): - (void)drawView: (dynamicRenderData)dynamicData How it's called w/in the controller: //controller [glview draw: [world getDynRenderData]]; //glview (within draw) [renderer drawView: dynamicData];

• Good open source analytics/stats software in PHP?

  - by makeee

  The url shortening service I'm building needs to display some basic click stats to users: # of clicks, conversions, referring domains, and country (filterable by a date range). I'll possibly want more advanced stats in the future. Is there existing open source software that will allow me to pass events to it and then easily display a bar or line graph of that event (for example, a line graph of "conversions" between two specified dates). It seems like something like this should exist and would be much easier then building the whole thing from scratch. I know there are graphing scripts, but that still requires me to format the data (usually as an xml file) and then pass it to the graph. I'm looking for something a bit more complete, which I can just feed the events and then it does everything else.

• UITableView cellForRowAtIndexPath occasionally not called?

  - by Tobster

  I'm developing a graphing application that on the main navigation/tab view displays a UIView that renders a graph using openGL. Beneath that view is a UITableView that displays the list of elements on the graph, and an add button. Occasionally, when the user clicks on another tab, and then returns to the graph view tab, the table view does not get redrawn. I have a [tableView reloadData] method being called in the navigation controllers' (also the table view's delegate and data source) viewDidAppear method. numberOfSectionsInTableView and numberOfRowsInSection get called, but cellForRowAtIndexPath does not despite both latter methods returning positive values. This is an intermittant problem, only happening some of the time, but it's not clear what (if anything) influences this. Does anyone have any ideas?

• Connecting data to a GUI - OOP

  - by tau

  I have an application with several graphs and tables on it. I worked fast and just made classes like Graph and Table that each contained a request object (pseudo-code): class Graph { private request; public function setDateRange(dateRange) { request.setDateRange(dateRange); } public function refresh() { request.getData(function() { //refresh the display }); } } Upon a GUI event (say, someone changes the date range dropdown), I'd just call the setters on the Graph instance and then refresh it. Well, when I added other GUI elements like tables and whatnot, they all basically had similar methods (setDateRange and other things common to the request). What are some more elegant OOP ways of doing this? The application is very simple and I don't want to over-architect it, but I also don't want to have a bunch of classes with basically the same methods that are just routing to a request object. I also don't want to set up each GUI class as inheriting from the request class, but I'm open to any ideas really.

• How to resize pdf graphics produced in R using Illustrator

  - by user1648516

  I am making plots in R using the pdf() command. Graphs look perfect and resize nicely in Acrobat Reader. My usual workflow includes manipulating labels etc. in Illustrator, saving as .eps for submission to publishers or inserting in Word. All works fine for single graphs. Now I am trying to combine 4 graphs into one by manually putting them together in an A4 Illustrator document. However, when I resize the standard 7x7 inches pdf graph in Illustrator to fit in one column of an A4 page (ca 3.4 inches wide), all proportions get screwed up, e.g. lines and symbols outlines become way too thick. Using pdf(..., width=3.4, height=3.4) in R messes up all the symbol and font sizes so carefully chosen to produce the original graph. Why can't I resize the graph within Illustrator the same way I can resize the pdf e.g. in Acrobat Reader?

• Selecting a portion of a JSON array and applying variables in javascript or jquery

  - by user1644609

  I am retrieving a JSON file that returns its results like what you see below. The JSON has 365 days worth of data. I would like to create "views" of this JSON using javascript, one which pulls the last 10 days, then 1 month, 6 months, etc. After the getJSON function I am doing this to get a string as JSON, then turn it into an object and will then graph it. So I would like each "view" to be an object for the specified timeframe (using the one JSON). The obj_10days, obj_1month, etc variables would then be plotted. var $ graph = data ; var obj = $ . parseJSON ( $ graph ) ; JSON: [ { "Low": 8.63, "Volume": 14211900, "Date": "2012-10-26", "High": 8.79, "Close": 8.65, "Adj Close": 8.65, "Open": 8.7 }, { "Low": 8.65, "Volume": 12167500, "Date": "2012-10-25", "High": 8.81, "Close": 8.73, "Adj Close": 8.73, "Open": 8.76 }, { "Low": 8.68, "Volume": 20239700, "Date": "2012-10-24", "High": 8.92, "Close": 8.7, "Adj Close": 8.7, "Open": 8.85 }, Any help is appreciated, thank you!

• Entity Framework v1 &hellip; Brief Synopsis and Tips &ndash; Part 2

  - by Rohit Gupta

  Using Entity Framework with ASMX Web sErvices and WCF Web Service: If you use ASMX WebService to expose Entity objects from Entity Framework... then the ASMX Webservice does not  include object graphs, one work around is to use Facade pattern or to use WCF Service. The other important aspect of using ASMX Web Services along with Entity Framework is that the ASMX Client is not aware of the existence of EF v1 since the client solely deals with C# objects (not EntityObjects or ObjectContext). Since the client is not aware of the ObjectContext hence the client cannot participate in change tracking since the client only receives the Current Values and not the Orginal values when the service sends the the Entity objects to the client. Thus there are 2 drawbacks to using EntityFramework with ASMX Web Service: 1. Object state is not maintained... so to overcome this limitation we need insert/update single entity at a time and retrieve the original values for the entity being updated on the server/service end before calling Save Changes. 2. ASMX does not maintain object graphs... i.e. Customer.Reservations or Customer.Reservations.Trip relationships are not maintained. Thus you need to send these relationships separately from service to client. WCF Web Service overcomes the object graph limitation of ASMX Web Service, but we need to insure that we are populating all the non-null scalar properties of all the objects in the object graph before calling Update. WCF Web service still cannot overcome the second limitation of tracking changes to entities at the client end. Also note that the "Customer" class in the Client is very different from the "Customer" class in the Entity Framework Model Entities. They are incompatible with each other hence we cannot cast one to the other. However the .NET Framework translates the client "Customer" Entity to the EFv1 Model "customer" Entity once the entity is serialzed back on the ASMX server end. If you need change tracking enabled on the client then we need to use WCF Data Services which is available with VS 2010. ====================================================================================================== In WCF when adding an object that has relationships, the framework assumes that every object in the object graph needs to be added to store. for e.g. in a Customer.Reservations.Trip object graph, when a Customer Entity is added to the store, the EFv1 assumes that it needs to a add a Reservations collection and also Trips for each Reservation. Thus if we need to use existing Trips for reservations then we need to insure that we null out the Trip object reference from Reservations and set the TripReference to the EntityKey of the desired Trip instead. ====================================================================================================== Understanding Relationships and Associations in EFv1 The Golden Rule of EF is that it does not load entities/relationships unless you ask it to explicitly do so. However there is 1 exception to this rule. This exception happens when you attach/detach entities from the ObjectContext. If you detach an Entity in a ObjectGraph from the ObjectContext, then the ObjectContext removes the ObjectStateEntry for this Entity and all the relationship Objects associated with this Entity. For e.g. in a Customer.Order.OrderDetails if the Customer Entity is detached from the ObjectContext then you cannot traverse to the Order and OrderDetails Entities (that still exist in the ObjectContext) from the Customer Entity(which does not exist in the Object Context) Conversely, if you JOIN a entity that is not in the ObjectContext with a Entity that is in the ObjContext then the First Entity will automatically be added to the ObjContext since relationships for the 2 Entities need to exist in the ObjContext. ========================================================= You cannot attach an EntityCollection to an entity through its navigation property for e.g. you cannot code myContact.Addresses = myAddressEntityCollection ========================================================== Cascade Deletes in EDM: The Designer does not support specifying cascase deletes for a Entity. To enable cascasde deletes on a Entity in EDM use the Association definition in CSDL for the Entity. for e.g. SalesOrderDetail (SOD) has a Foreign Key relationship with SalesOrderHeader (SalesOrderHeader 1 : SalesOrderDetail *) if you specify a cascade Delete on SalesOrderHeader Entity then calling deleteObject on SalesOrderHeader (SOH) Entity will send delete commands for SOH record and all the SOD records that reference the SOH record. ========================================================== As a good design practise, if you use Cascade Deletes insure that Cascade delete facet is used both in the EDM as well as in the database. Even though it is not absolutely mandatory to have Cascade deletes on both Database and EDM (since you can see that just the Cascade delete spec on the SOH Entity in EDM will insure that SOH record and all related SOD records will be deleted from the database ... even though you dont have cascade delete configured in the database in the SOD table) ============================================================== Maintaining relationships in Code When Setting a Navigation property of a Entity (for e.g. setting the Contact Navigation property of Address Entity) the following rules apply : If both objects are detached, no relationship object will be created. You are simply setting a property the CLR way. If both objects are attached, a relationship object will be created. If only one of the objects is attached, the other will become attached and a relationship object will be created. If that detached object is new, when it is attached to the context its EntityState will be Added. One important rule to remember regarding synchronizing the EntityReference.Value and EntityReference.EntityKey properties is that when attaching an Entity which has a EntityReference (e.g. Address Entity with ContactReference) the Value property will take precedence and if the Value and EntityKey are out of sync, the EntityKey will be updated to match the Value. ====================================================== If you call .Load() method on a detached Entity then the .Load() operation will throw an exception. There is one exception to this rule. If you load entities using MergeOption.NoTracking, you will be able to call .Load() on such entities since these Entities are accessible by the ObjectContext. So the bottomline is that we need Objectontext to be able to call .Load() method to do deffered loading on EntityReference or EntityCollection. Another rule to remember is that you cannot call .Load() on entities that have a EntityState.Added State since the ObjectContext uses the EntityKey of the Primary (Parent) Entity when loading the related (Child) Entity (and not the EntityKey of the child (even if the EntityKey of the child is present before calling .Load()) ====================================================== You can use ObjContext.Add() to add a entity to the ObjContext and set the EntityState of the new Entity to EntityState.Added. here no relationships are added/updated. You can also use EntityCollection.Add() method to add an entity to another entity's related EntityCollection for e.g. contact has a Addresses EntityCollection so to add a new address use contact.Addresses.Add(newAddress) to add a new address to the Addresses EntityCollection. Note that if the entity does not already exist in the ObjectContext then calling contact.Addresses.Add(myAddress) will cause a new Address Entity to be added to the ObjContext with EntityState.Added and it will also add a RelationshipEntry (a relationship object) with EntityState.Added which connects the Contact (contact) with the new address newAddress. Note that if the entity already exists in the Objectcontext (being part theOtherContact.Addresses Collection), then calling contact.Addresses.Add(existingAddress) will add 2 RelationshipEntry objects to the ObjectStateEntry Collection, one with EntityState.Deleted and the other with EntityState.Added. This implies that the existingAddress Entity is removed from the theOtherContact.Addresses Collection and Added to the contact.Addresses Collection..effectively reassigning the address entity from the theOtherContact to "contact". This is called moving an existing entity to a new object graph. ====================================================== You usually use ObjectContext.Attach() and EntityCollection.Attach() methods usually when you need to reconstruct the ObjectGraph after deserializing the objects as received from a ASMX Web Service Client. Attach is usually used to connect existing Entities in the ObjectContext. When EntityCollection.Attach() is called the EntityState of the RelationshipEntry (the relationship object) remains as EntityState.unchanged whereas when EntityCollection.Add() method is called the EntityState of the relationship object changes to EntityState.Added or EntityState.Deleted as the situation demands. ========================================================= LINQ To Entities Tips: Select Many does Inner Join by default.   for e.g. from c in Contact from a in c.Address select c ... this will do a Inner Join between the Contacts and Addresses Table and return only those Contacts that have a Address. ======================================================== Group Joins Do LEFT Join by default. e.g. from a in Address join c in Contact ON a.Contact.ContactID == c.ContactID Into g WHERE a.CountryRegion == "US" select g; This query will do a left join on the Contact table and return contacts that have a address in "US" region The following query : from c in Contact join a in Address.Where(a1 => a1.CountryRegion == "US") on c.ContactID  equals a.Contact.ContactID into addresses select new {c, addresses} will do a left join on the Address table and return All Contacts. In these Contacts only those will have its Address EntityCollection Populated which have a Address in the "US" region, the other contacts will have 0 Addresses in the Address collection (even if addresses for those contacts exist in the database but are in a different region) ======================================================== Linq to Entities does not support DefaultIfEmpty().... instead use .Include("Address") Query Builder method to do a Left JOIN or use Group Joins if you need more control like Filtering on the Address EntityCollection of Contact Entity =================================================================== Use CreateSourceQuery() on the EntityReference or EntityCollection if you need to add filters during deferred loading of Entities (Deferred loading in EFv1 happens when you call Load() method on the EntityReference or EntityCollection. for e.g. var cust=context.Contacts.OfType<Customer>().First(); var sq = cust.Reservations.CreateSourceQuery().Where(r => r.ReservationDate > new DateTime(2008,1,1)); cust.Reservations.Attach(sq); This populates only those reservations that are older than Jan 1 2008. This is the only way (in EFv1) to Attach a Range of Entities to a EntityCollection using the Attach() method ================================================================== If you need to get the Foreign Key value for a entity e.g. to get the ContactID value from a Address Entity use this :                                address.ContactReference.EntityKey.EntityKeyValues.Where(k=> k.Key == "ContactID")
