Based on the free particle model of quantum system
the Multi-scale Free Particle Optimization Algorithm (MFPOA) is proposed
and the internal mechanism of the algorithm is studied on the basis of the physical model. Through analogy between quantum system and optimization system
the solving process of optimization problem is transformed into the motion process of particles under the microscopic system. The parameter setting of free particle optimization is studied on MATLAB simulation platform
and the differences between the algorithm and similar search mechanism are analyzed. Finally
experiments show that MFPOA is more suitable for solving single-mode functions
and more iterations are needed to solve complex multi-mode functions.
