We study the worst-case performance of the maximal matching heuristic applied to the Minimum Vertex Cover and Minimum Maximal Matching problems, through a careful analysis of tight examples. We show that the tight worst-case approximation ratio is asymptotic to \\\({m min}\\\, \\\{2, 1/...
We present a novel refined analysis of this greedy heuristic which enables us to: (1) reduce the enumeration in the tight (1e1)-approximation of [Sviridenko 04] from subsets of size three to two; (2) present an improved upper bound of 0.42945 for the classic algorithm which returns the ...

Such an analysis is expected to deliver valuable criteria-better than the worst-case complexity-for the efficiency of an algorithm in practice. The author has done much work of that kind in the field of linear programming. Based on that experience he gives some insight into the general ...
TL;DR: This is an informal summary of our recent paper On the Unreasonable Effectiveness of the Greedy Algorithm: Greedy Adapts to Sharpness with Mohit Singh, and Alfredo Torrico, where we adapt the sharpness concept from convex optimization to explain t
It uses as bounding procedure a 2-machine subproblem that gives a tight lower bound, but it cannot be computed in polynomial time. An efficient branch-and-bound algorithm developed by Haouari and Ladhari [20] is used to solve the subproblem but it is expensive in time (for this reason ...
