Recently I competed in nation wide programming contest finals. Not unexpectedly all problems were algorithmic. I lost (40 points out of 600. Winner got ~300). I know why I lost very well - I don't know how to find actual problem in those obfuscated tasks which are life-blood of every competition.…

I'm trying to implement a genetic algorithm that will calculate the minimum of the Rastrigin functon and I'm having some issues.
I need to represent the chromosome as a binary string and as the Rastrigin's function takes a list of numbers as a parameter, how can decode the chromosome to a list of…

I'm new to coding , learning it since last year actually.
One of my worst habits is the following:
Often I'm trying to create a solution that is too big , too complex and doesn't achieve what needs to be achieved, when a hacky kludge can make the fit.
One last example was the following (see paste…

I have successfully implemented both but I want to improve the evaluation function by automatically tuning the weights assigned to its features. At this point am totally confused about the…

What are some clever (not ordinary) ways of implementing data structures in C, and what are some data structures that should be used more often?
For example, what is the most effective way (generating minimal overhead) to implement a directed and cyclic graph with weighted edges in C?
I know that…

When we design applications, we generally end up with the same tiered sets of data structures:
A persistent data structure that is described using DDL and implemented as RDBMS tables and columns.
A set of domain objects that consist primarily of data structures, usually combined with business-rule…

I am a newbie into the corporate world recently graduated in computers. I am a java/groovy developer. I am a quick learner and I can learn new frameworks, APIs or even programming languages within considerably short amount of time. Albeit that, I must confess that I was not so strong in data structures…

Hello,
I have to design a data structure that is to be used in a multi-threaded environment. The basic API is simple: insert element, remove element, retrieve element, check that element exists. The structure's implementation uses implicit locking to guarantee the atomicity of a single API call.…

There is a large stream of numbers coming in such as 5 6 7 2 3 1 2 3 .. What kind of data structure is suitable for this problem given the constraints that elements must be inserted in descending order and duplicates should be eliminated.
I am not looking for any code just ideas? I was thinking…
