WebGiven a graph G= (V,E), a cut is a partition of V into two subsets S and V-S. The size of a cut is the number of edges with one extremity in S and the other in V-S. The MAX CUT problem is to find a cut with a size larger or equal to … Web14 apr. 2024 · Secondly, generalizing the result of Alon, we allow the graph to have triangles, and show that if the number of triangles is a bit less than in a random graph with the same density, then the graph has large surplus. For regular graphs our bounds on the surplus are sharp.
