Webexample, graph partitioning algorithms also play an important role in areas such as VLSI layout, sparse linear system solving and circuit testing and simulation. The above graph … WebThe graph partitioning problem as described by Kernighan and Lin is “given a graph G with costs on its edges, partition the nodes of G into subsets no larger than a given maximum size, so as to minimize the total cost of the edges cut” To start we will try to solve the problem with two partitions before generalizing the number of partitions
