WebUnfortunately, the bisection problem is NP-hard [20] for general graphs, with a best known approximation ratio of O(logn) [38]. Only some restricted graph classes, such as grids without holes [17] and graphs with bounded treewidth [27], have known polynomial-time solutions. In practice, there are numerous general-purpose heuristics for graph parti- WebThe cutwidth is greater than or equal to the minimum bisection number of any graph. This is minimum possible number of edges from one side to another for a partition of the vertices into two subsets of equal size (or as near equal as possible). The cutwidth is less than or equal to the maximum degree multiplied by the graph bandwidth, the ...
