2、部最優(yōu)解等缺陷,建立了相應(yīng)的罰因子的評價機制,生成了兩類進化子種群,運用改進遺傳算法同時對不同種群進行操作,并將其應(yīng)用在灤河下游六水庫聯(lián)合供水優(yōu)化調(diào)度中。實例計算結(jié)果表明,用該算法求解水庫群供水優(yōu)化調(diào)度問題,結(jié)果可靠、合理,計算效率高。關(guān)鍵詞:水庫群供水優(yōu)化調(diào)度;遺傳算法;協(xié)同進化;罰函數(shù)中圖分類號:S11文獻標(biāo)志碼:AResearchonCo-EvolutionaryGeneticAlgorithmforReservoirOptimizationWaterSupplyDispatchingWANFang,HUANGQiang‘,YUANWenlin,QIULin(1.KeyLabofN
