This thesis is aimed to solve an AI problem using Java language. So firstly speaking about the problem. I have made a research on the internet going through several websites to choose a problem. That can be solved by AI and I have found that creating an algorithm and an application to solve the problem of choosing a squad for a football team on every match and against every opponent is a very interesting question to be solved. Which players could join which matches and whether the players are going to be giving their best performances.
