A basic study of Integer Particle Swarm Optimization having deterministic dynamics

In this paper, we propose a method celled Integer Particle Swarm Optimization based on Piecewise Constant Oscillator (IPSO-PCO). Well known Particle Swarm Optimization (PSO) is pointed out that it is hard to analyze particle behavior and to implementation of hardware. For this problem, some deterministic PSO have been proposed. Discretization is also desired in terms of implementation of hardware and application to combinational optimization problems. This paper proposes a deterministic and discrete method. We compare IPSO-PCO with some methods of PSO which discretized by repositioned to near lattice point and verify the effectiveness of propose method.
