A stationary point which is neither a local maximum nor a local minimum point is called a saddle point. 一个既不是局部极大点又不是局部极小点的平稳点称为一个鞍点。
Since ergodicity is an effective mechanism to avoid trapping into local minima in the searching process, chaos has been a novel and potential optimization tool. 由于遍历性可作为避免搜索过程陷入局部极小的有效机制，因此混沌理论已成为一种新颖且有潜力的优化工具。
