Summary
In this study, ε constrained particle swarm optimizer εPSO, which is the combination of the ε constrained method and particle swarm optimization, is proposed to solve constrained optimization problems. The ε constrained methods can convert algorithms for unconstrained problems to algorithms for constrained problems using the ε level comparison, which compares the search points based on the constraint violation of them. In the ε PSO, the agents who satisfy the constraints move to optimize the objective function and the agents who don’t satisfy the constraints move to satisfy the constraints. Also, the way of controlling ε-level is given to solve problems with equality constraints. The effectiveness of the ε PSO is shown by comparing the ε PSO with GENOCOP5.0 on some nonlinear constrained problems with equality constraints.
