Thus the value of the function at any grid point is the average of its values at the immediately neighboring points. 因此，任一结点上的函数值就等于其直接邻点上函数值的平均。
Through multiple generation calculation, the minimum point of penalty function value was obtained, then the optimalc reduction distribution was found. 通过粒子群多代运算，求出罚函数值最小点，得到压下负荷最佳分配点。
