-A search and optimization library, focusing on [metaheuristics](http://en.wikipedia.org/wiki/Metaheuristic). Currently includes implementations for: [hill climbing search](http://en.wikipedia.org/wiki/Hill_climbing), [simulated_annealing](http://en.wikipedia.org/wiki/Simulated_annealing) and [genetic algorithms](http://en.wikipedia.org/wiki/Genetic_algorithm).
