Interface Problem

All Known Implementing Classes:

GDProblem, MSTProblem, SATProblem, TSPProblem

public interface Problem

This interface is implemented by problems, and is intended for those who want to create an optimization problem. If you are an algorithm writer, you don't need to understand this interface but instead the inheriting interface for the particular problem, such as TSPAlgorithm.
