LAPJV  JonkerVolgenant Algorithm for Linear Assignment Problem 1.0 Description 

Description: The JonkerVolgenant algorithm is much faster than the famous Hungarian algorithm for the Linear Assignment Problem (LAP). This Matlab implementation is modified from the original C++ code made by Roy Jonker, one of the inventors of the algorithm. It is about 10 times faster than the munkres code (v2.2) of the author. It can solve a 1000 x 1000 problem in about 3 seconds in a normal Intel Centrino processor.
V1.1 returns the dual variables and the reduced cost matrix as well. V1.2 can deal with nonsquare assignment problems. V2.0 is faster for problems with a large range of costs. V2.1 includes an option to change the cost resolution to improve performance for some problems. v2.2 removes a small bug to avoid NAN for 1x1 case. v2.3 removes a small bug to handle a cost matrix with all inf's. v2.4 fixes a bug associated with resolution to address the known problem of the algorithm.

This function contains the well known greedy algorithm for solving Set Cover problem (ChvdodAtal, 1979), with two small modifications: * In case of more than one possible choice at a certain step, the biggest set is chosen; * Once the solution is found, we check the selected sets to find a better cover solution, removing a set if is a subset of the union of the other set.
