A Method of Modifier Algorithm of Constrained Complex Method in Concave Feasible Fields

The constrained complex method is one of the important ways to resolve the problem of nonlinear optimization.The iterative calculating method of constrained complex method in concave feasible fields is discussed in this paper. In view of the situation that the central point of complex is out of the feasible fields, the common complex algorithm is modified and a new method of iterative calculation is provided for engineering calculation. At the same time, through the contrasting calculation of an engineering optimization problem, the astringency and engineering usability of this modifier algorithm are proved.The computation results show that the method of modifier algorithm of constrained complex method in concave feasible fields,proposed in this paper, is effective.
