Bipartite weighted matchingCombinatorial optimizationHandwritten Chinese character recognitionIn this paper, a greedy matching algorithm with geometric constraint for solving the polygonal arcs matching (boundary line segments matching) is proposed. Assume the matched cost and the unmatched penalty of each ...

This may be expected, as the algorithm does not consider edges. The IsoRank algorithm also aligns edges poorly (96 of 466 EAs, 21%), as it primarily focuses on the alignment of similar nodes. The bipartite nature of the networks also causes unusual behaviour: the R similarity score in ...

In this case (or the bipartite case, for that matter), greed won’t work in general. However, by some freak coincidence, all the compatibility numbers happen to be distinct powers of two. Now, what happens? Let’s first consider what a greedy algorithm would look like here and then see...

A bipartite graph G(U,V;E) that admits a perfect matching is given. One player imposes a permutation pi over V, the other player imposes a permutation sigma over U. In the greedy matching algorithm, vertices of U arrive in order sigma and each vertex is matched to the highest (under ...
Since Tinhofer proposed the MinGreedy algorithm for maximum cardinality\nmatching in 1984, several experimental studies found the randomized algorithm\nto perform excellently for various classes of random graphs and benchmark\ninstances. In contrast, only few analytical results are known. We show that...
