摘　　要：临界水深非线性约束优化计算建模,应用种群竞争算法进行求解.本文提出种群竞争算法是一种新型全局优化算法,运用种群间与种群内"双重竞争"寻优机制.通过实例说明并与其它方法比较,在求解临界水深计算时,收敛速度快,精度高,编写简单.试算法得到结果还可通过优化方法修正.The nonlinear constrained optimization calculation of critical water depth problem be solved by a new optimization algorithm-Competitive Population Algorithm which through the ＂double competition＂ in population and its individuality advanced by this article. Competitive Population Algorithm is a new global optimization algorithm. Through example illustrating and compared with others methods, this article＇s optimization solve the critical water depth has some merits such as program simple,speedy constriction,exact result. The result come from cut-be-corrected by optimization method.
