Kernighan_lin_bisection
WebKernighan-Lin Algorithm falls under this category. The KL Algorithm is applied to travelling salesman problem [3] and in the design of VLSI circuits [4]. II. KERNIGHAN – LIN ALGORITHM KL algorithm is a heuristic procedure for solving the graph partitioning problem [5]. It is most widely used in the area of digital and VLSI circuits design. Web1 feb. 2024 · The Kernighan–Lin Bipartition algorithm is a technique for segregating the graph between nodes and vertices into subsets which are efficiently linked together. The primary goal of this algorithm is to partition the network graph (input) into two equal subsets.
