The greedy algorithm is one of the simplest algorithms to implement:take the closest/nearest/most optimal option, and repeat.It always chooses which element of a set seems to be the best at the moment. It never changes its mind at a later point. Greedy algorithms are “top-down”, which ...
In 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 line segment are given, as well as any two matched pairs in the matching which ...
Summary of the problem: Given a tree find a largest set of edges such that no two edges share an endpoint (maximum matching), or to find minimal set of nodes such that each node outside the set must be adjacent to at least one node in the set (minimum vertex cover). Usual algorithm...
Since Tinhofer proposed the MinGreedy algorithm for maximum cardinality matching in 1984, several experimental studies found the randomized algorithm to perform excellently for various classes of random graphs and benchmark instances. In contrast, only few analytical results are known. We show that ...
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 ...

In the GCM algorithm, we first propose a greedy strategy for detecting candidate matching users using Profile Attributes Similarity (PAS) and User Surrounding Score (USS). We then define the User Matching Score (UMS), which combines PAS with network structures, to greedily determine matched users...

We consider the following randomized algorithm for finding a matching M in an arbitrary graph G = (V, E). Repeatedly, choose a random vertex u, then a random neighbour v of u. Add edge {u, v} to M and delete vertices u, v from G along with any vertices that become isolated. Our...
We follow this trend and consider the problem formulated in the oblivious setting, in which the vertex set of a graph is known to the algorithm but not the edge set. The algorithm can make queries for the existence of the edge between any pair of vertices but must include the edge into ...
