I have a list of integers keys = [18, 99, 86, 61, 66, 81, 98, 19, 91, 16, 69, 88, 89, 68, 11, 96] I'd like to find all permatutations of this list such that for each permutation elements 0 th...

Why is the complexity of Arc-Consistency Algorithm O(cd3)?

I'm working on source-to-source transformer for Java 6*1). I need to maintain negative information as well as positive information, so I have to implement the small constraint system for the tran...

Anyone can explain to me the AC-1, AC-2 and AC-3 algorithms ? I have to understand them and implement them with code. But first, I want to understand them really good, But they are just too tough t...

Problem statement: Given four words, place them inside a m x n grid of squares such that the area of the grid is as small as possible. Words must run from left to right and from top to bott...

Abstract problem description: The way I see it, unparsing means to create a token stream from an AST, which when parsed again produces an equal AST. So parse(unparse(AST)) = AST holds. This is...

I'd just like someone to verify whether the following problem is NP-complete or if there is actually a better/easier solution to it than simple brute-force combination checking. We have a sort-of ...

What are the relevant differences, in terms of performance and use cases, between simulated annealing (with bean search) and genetic algorithms? I know that SA can be thought as GA where the popul...
