in which I point all flows ) –sum ( the Nether Stream where I point all flows out )Assuming that the mi is greater than 0and that the point must also flow out of the free stream to mi , then we connect a single mi edge from the source point to that point. Assuming that Mi is less than 0, this point must also flow in The free stream of MI. So we'll go from that point to the edge of a Mi to the meeting point. Suppose the maximum flow of the s->t is calculated to see if the full stream ( The n
