本工程将ffmpeg项目中的ffplay播放器(ffplay.c)移植到了VC的环境下。
并且使用MFC做了一套简单的界面。
This software transplant ffplay to Microsoft VC++ environment.
And use MFC to build a simple Graphical User Interface.
Particle swarm optimization (PSO) is a population based stochastic optimization technique developed by Dr. Eberhart and Dr. Kennedy in 1995, inspired by social behavior of bird flocking or fish schooling. Each particle keeps track of its coordinates in the problem space which are associated with the best solution (fitness) it has achieved so far. (The fitness value is also stored.)
This value is called pbest. Another "best" value that is tracked by the particle swarm optimizer is the best value, obtained so far by any particle in the neighbors of the particle. This location is called lbest. when a particle takes all the population as its topological neighbors, the best value is a global best and is called gbest. Following is the steps of PSO:
