说明：  本代码为经典PSO微粒群算法，通过修改w值，使得PSO的搜索在全局与局部之间得到最优(The code for the classic PSO particle swarm algorithm, by modifying the w value, makes the PSO search between the global and local optimal)

趋势面分析是拟合数学曲面的一种统计方法。通常要找到一个合适的曲面精确表达实际问题往往比较困难，但却可以利用多项式函数来近似逼近它。(trend surface analysis is fitting surfaces of a mathematical statistical methods. Usually to find a suitable surface accurately reflect the actual problems are often more difficult, but polynomial function can be used to approximating it.)
