1、杭州電子科技大學(xué)碩士學(xué)位論文3.考慮到云環(huán)境的多樣性、云規(guī)模的差異性，為了讓PSO_ACO算法更具適應(yīng)性，第四章從最優(yōu)解的分布狀態(tài)入手，對(duì)原有算法的信息素更新規(guī)則進(jìn)行改進(jìn)，完成了自適應(yīng)PSO_ACO算法的設(shè)計(jì)，最后通過(guò)實(shí)驗(yàn)表明這種自適應(yīng)調(diào)度算法具有比PSO_ACO更好的全局搜索最優(yōu)解的能力和使資源負(fù)載均衡能力。關(guān)鍵詞：云計(jì)算，任務(wù)調(diào)度，負(fù)載均衡，蟻群算法，自適應(yīng)II杭州電子科技大學(xué)碩士學(xué)位論文ABSTRACTCloudcomputingisaEmergingtechnologywhichisdevelopedfro
