Web23 mei 2024 · A valid max flow sends $1/2$ units of flow across each edge of the bipartite graph. This gives a negative answer to your first question. On the other hand, the integral flow theorem guarantees that there exists an integral max flow, and such a max flow can be found algorithmically. An integral max flow does correspond to a maximum matching. WebA linear program (LP) is defined as Min (Minimize) z = ctx subject to Ax ≤ b, x ≥ 0 (null column vector), where A= [aij] is an m×n numerically specified matrix, b= [bi] is an m × 1 numerically given column vector and c = [cj] is an n × 1 numerically specified column vector.
