Google Hash Code is a programming competition by Google, which evolves around finding an optimized solution using a heuristic approach. This year's problem is about optimizing the scanning process of Google Book. The constraints are that each library has a certain number of books which are more or less popular. Additionally, some books take longer to scan than others. The question is how to efficiently scan the most books in a short amount of time taking their popularity into account. More detailed information can be found in the hashcode_problem directory. We used 3 different approaches which are a random algorithm and an greedy algorithm which tried to determined which library to scan first.
