Combinatorics library (Silverlight for Windows Phone)
I recently found a very nice article at CodeProject on Combinatorics algorithms implementation (specifically Permutations, Combinations and Variations with Repetition option) using C# Generics: http://www.codeproject.com/KB/recipes/Combinatorics.aspx It uses a lexicographic algorithm, so it allows one to ask for “next” permutation/combination/variation from the collection of all possible ones, in the spirit of C++ Standard Library’s (STL) “next_permutation” [...]
