This is a basic upstream/downstream network stream.The upstream and downstream network stream algorithms are based entirely on the paper "a simple method for solving the network with the upper and lower bounds of traffic" and a model for the application of the largest stream in the informatics competition.Then I will talk about it in more detail.The specific solution is no longer mentioned.

SSIS event-based upstream transmission (detailed) In SSIS, a Package is an ordered combination of Task components and has a hierarchy. The Package is at the top Level of the hierarchy (Root Level). For a Parent-child Package structure, the Parent Package) other packages are called through the Execute Package Task component. The called Package is a sub-Package, and the parent Package is the upper-level and top-level Package of the sub-Package, which is

Feasible stream with no source sink Arc traffic restriction condition B (u, v) F (u, v) = B (u, v) + F1 (u, v ), Σ (B (u, v) + F1 (u, v) = Σ (B (V, W) + F1 (V, W )) Σ B (u, v)-Σ B (V, W) = Σ F1 (V, W)-Σ F1 (u, v) If a feasible stream exists, 0 You can add super source S and super sink T. Assume that the traffic limit of an edge (u, v) is [B, c], equivalent to S → v traffic B, u → T traffic B, U → v traffic c-B. We can perform the maximum stream from S to T. If the load is full, the lower str

1. Non-source sink upstream and downstream feasible streams For a directed edge (u, v), the upper bound is A, and the lower bound is B: (1) the SS to V capacity is B (2) The capacity from u to TT is B. (3) The capacity from u to V is a-B. Calculate the maximum SS-TT stream. A Feasible stream exists only when maxflow = sigma (I, t) = sigma (S, I ). 2. The smallest stream at the upper and lower bound of the Source Sink If the source image has no
