概要	The penalty function method has been widely used to solve constrained optimization problems. In the method,an extended objective function, which is the sum of the objective value and the constraint violation weighted by the penaltycoefficient, is optimized. However, it is difficult to control the coefficient properly because the proper control dependson each problem. Recently, the equivalent penalty coefficient (EPC) method, which is a new adaptive penalty method for population-based optimization algorithms (POAs), has been proposed.In this study, we propose to apply the EPC method to particle swarm optimization (PSO) where a new solution is compared with the best solution found so far. In order to improve theperformance of constrained optimization, a mutation operation is also proposed.
