The max-ﬂow algorithm is used to ﬁnd the minimum cut of the graph, which corresponds to a minimum conﬁguration x! of E(x). The max-ﬂow algorithm requires a graph with non-negative edge weights, which means all quadratic terms must be submodular [10]: E ij(0,0)+E ij(1,1) ≤ E ij(0,1)+E ij(1 ... dvd to mp4 converter freeware download
