一种新的无约束优化方法

A New Unconstrained Optimization Method

提出一种新的无约束优化方法，此方法在确定搜索方向时，不需提供导数信息，仅需根据设计点附近“定向单元”的函数信息，便可确定出有效的搜索方向，进而较快地获得最优点。本方法算法原理简单，易于编程，经３个例题验证，取得了满意的结果。这说明了此方法的可靠性和正确性，为优化设计领域提供了一种新的优化算法。

A new unconstrained optimization method is proposed in this paper. Derived function are not necessary to determine searching direction by using this method. According to the functions of “directional element” near the selected point, it can find effective serching direction and acquire optimal point quickly. The algorithm principle of this method is simple and easy to be programed. It is correct and reliable by three examples and the results satisfy us. It provides a new method in optimum design domain.
