• Design pattern for isomorphic trees

  - by Peregring-lk

  I want to create a data structure to work with isomorphic tree. I don't search for a "algorithms" or methods to check if two or more trees are isomorphic each other. Just to create various trees with the same structure. Example: 2 - - - - - - - 'a' - - - - - - - 3.5 / \ / \ / \ 3 3 'f' 'y' 1.0…

• What is the usage of Splay Trees in the real world?

  - by Meena

  I decided to learn about balanced search trees, so I picked 2-3-4 and splay trees. What are the examples of splay trees usage in the real world? In this Cornell: http://www.cs.cornell.edu/courses/cs3110/2009fa/recitations/rec-splay.html I read that splay trees are 'A good example is a network router'. But from rest of the explanation seams like…

• How to find Sub-trees in non-binary tree

  - by kenny

  I have a non-binary tree. I want to find all "sub-trees" that are connected to root. Sub-tree is a a link group of tree nodes. every group is colored in it's own color. What would be be the best approach? Run recursion down and up for every node? The data structure of every treenode is a list of children, list of parents.…

  - by jelly

  Hi, note this is not homework. But can anyone tell me how you find the min/max height of B trees, 2-3-4 trees and binary search trees? Thanks

• Game Trees Conceptual Question

  - by Chris Corbin

  I am struggling to conceptually understand a question in a programming assignment for an algorithms class. The problem is dealing with a fictitious 2 player game, named Easy. The rules of the game are simple; each player may chose one of 4 integers {0-3} after which that integer is not available for the other player. The catch…

  - by jelly

  Hi, Could someone please explain to me the difference between B Trees and 2-3-4 Trees? And also how would you find the maximum and minimum height of each? Thanks

• B- trees, B+ trees difference

  - by dta

  In a B- tree you can store both keys and data in the internal/leaf nodes. But in a B+ tree you have to store the data in the leaf nodes only. Is there any advantage of doing the above in a B+ tree? Why not use B- trees instead of B+ trees everywhere? As intuitively they seem much faster. I mean why do you need to replicate the…

• Question on Binary Search Trees.

  - by AGeek

  Hi, I was thinking of implementing a binary search trees. I have implemented some very basic operations such as search, insert, delete. Please share your experiences as to what all other operations i could perform on binary search trees, and some real time operations(basic) that is needed every time for any given situation..…

  I decided to add to my game few trees, I already quake 3 model loader (md3) its for characters and method for texture drawing is store in *.ini file. I found a package of trees in MD3 and I have no problem with loading model alone, but there is a *.shader file and i have no idea how to load it to draw texture properly. Tree…

• Persistent (purely functional) Red-Black trees on disk performance

  - by Waneck

  I'm studying the best data structures to implement a simple open-source object temporal database, and currently I'm very fond of using Persistent Red-Black trees to do it. My main reasons for using persistent data structures is first of all to minimize the use of locks, so the database can be as parallel as possible. Also…

• Binary Trees in Scheme

  - by Javier

  Consider the following BNF defining trees of numbers. Notice that a tree can either be a leaf, a node-1 with one subtrees, or a node-2 with two subtrees. tree ::= (’leaf number) | (’node-1 tree) | (’node-2 tree tree) a. Write a template for recursive procedures on these trees. b. Define the procedure (leaf-count t)…

• .NET Expression Trees Tutorial

  - by zoman

  I've been looking for a good tutorial on Expression trees (C#) for a while, but no luck so far. Most of the stuff I've found on the Web was too high level and very basic. Does anyone know some decent tutorial that goes beyond the fundamentals?

• Built-in precedence in Expression Trees for math?

  - by jdk

  I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it (e.g. maybe through helper methods or classes)? I want to…

  The latest version of Google Earth is all about viewing 3D models of trees that we can see as we walk through the streets in Google Earth and integrated street views. Tech Crunch says ..trees are obviously a hugely important part of the Earth. To get them into Google Earth, the search giant has made 3D models of over…

• Why are trees shining in background?

  - by Kinected

  Currently I am creating a forest scene in the dark, and the trees are shining far away, but when I get close they are fine. I have the shaders set to "Nature/Tree Soft Occlusion [bark/leaves]", but they are still rendering strange far away, but close they are fine. I tried placing the trees in a folder named…

• Using Behavior Trees and Events together

  - by weichsem

  I am beginning to work with behavior trees and am unsure how events should be handled within the tree. Lets say we have a space game where the player is dogfighting with a handful of other ships, some friendly some not. The player destroys a ship and the rest of the hostile ships should then start to retreat. …

  I have a binary tree T which I would like to copy to another tree. Suppose I have a visit method that gets evaluated at every node: struct visit { virtual void operator() (node* n)=0; }; and I have a visitor algorithm void visitor(node* t, visit& v) { //do a preorder traversal using stack or…
