WebbThe algorithm of Karger [ 11 ], based on random edge contractions, can also solve in time; this was later improved to runtime by Karger and Stein [ 12 ]. There have been a number of improved deterministic algorithms [ 2, 5, 10, 15 ]: notably, the tree-packing result of Thorup [ 15] was sped up by Chekuri et al. [ 2] to runtime.

WebbKarger’s algorithm is a type of ‘random algorithm’ because every time we run it, it gives out a solution that can not be sure to be the best solution. The Karger’s algorithm for the minimum cut is to cut a graph into two disjoint subgraphs and we do it by eliminating a minimum number of edges in the graph. It chooses an edge of graph ... WebbKarger’s algorithm is a Monte Carlo algorithm for find- ing global minimum graph cuts, meaning that it has a fixed runtime but is not guaranteed to find the best cut. It is …
