题意:M台机器要生产n个糖果，糖果i的生产区间在(si, ti)，花费是k(pi-si)，pi是实际开始生产的时间机器,j从初始化到生产糖果i所需的时间Cij，花费是Dij,任意机器从生产糖果i到生产糖果j，需花费时间Eij,花费Fij求生产完所有糖果所需的最小时间？
题解:先把糖果拆点,s向i糖果连流量为1,费用为0,i+n糖果向t连流量为1,费用为0,n2+i机器向t连流量为1,费用为0的边,如果i能流向j,那么j连i+n一条边流量为1,费用为(ti-sj)k+dij,如果机器j能流向i+2n,那么连一条边流量为1,费用为(p-s)*k+d,假设i流向了j,那么说明j在i之后生产,而且保证了每台机器只生产一种糖果
