WebbKarger Randomized Contraction algorithm for finding Minimum Cut in undirected Graphs. Karger's algorithm is a randomized algorithm to compute a minimum cut of a … 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 ... fun id card maker
