B 宽度优先(种子染色法)5.关键路径几个定义: 顶点1为源点,n为汇点。a. 顶点事件最早发生时间Ve[j], Ve [j] = max{ Ve [j] + w[I,j] },其中Ve (1) = 0;b. 顶点事件最晚发生时间 Vl[j], Vl [j] = min{ Vl[j] – w[I,j] },其中 Vl(n) = Ve(n);c. 边活动最早开始时间 Ee[I], 若边I由j,k表示,则Ee[I] = Ve[j];d. 边活动最晚开始时间 El[I], 若边I由j,k表示,则El[I] = Vl[k] – w[j,k];若 Ee[j] = El[j] ,则活动j为关键活动,由关键活动组成的路径为关键路径。求解方法:a. 从源点起topsort,判断是否有回路并计算Ve;
