Professional klika solver

The aim of this program is to showcase the possibilities of genetic algorithm on the example of solving the maximum clique problem.
The algorithm finds the biggest clique in an undirected graph (clique is a subset of graph's vertices such that every two vertices in the subset are connected by an edge).
The algorithm uses many mechanisms used in genetic algorithms, such as: mutation, crossover, selection. The GUI allows using different versions of these mechanisms and changing other parameters.
Co-creators: Michal Pierog, Witold Baran. Technology: Java.
