  • ford-max-flow
    解决最小费用最大流问题,一般有两条途径。一条途径是先用最大流算法算出最大流,然后根据边费用,检查是否有可能在流量平衡的前提下通过调整边流量,使总费用得以减少?只要有这个可能,就进行这样的调整。调整后,得到一个新的最大流。(Minimum cost maximum flow problem to solve, there are generally two ways. One way is to use a maximum flow algorithm to calculate the maximum flow, then the cost side, check whether it is possible under the premise of the flow balance by adjusting the edge flow, so that the total cost can be reduced? As long as this possible, for such adjustments. Adjusted to obtain a new maximum flow.)
