The Applicaiton of OEA in the Geometric Constraint Solving

In this paper we propose a new optimization algorithm - organizational evolutionary algorithm (OEA) and apply it into the geometric constraint solving. We transfer the geometric constraint problem into a set of nonlinear equations substantially. In OEA the colony is composed of the organizations. Three organizational evolutionary operators - split operator, merging operator and coordinating operator can lead the colony to evolve. These three kinds of operators have different functions in the algorithm. The experiment shows that OEA has good capability in the geometric constraint solving
