The algorithm starts with an empty matching and then iteratively improves it by adding edges, one at a time, to build augmenting paths in the matching M. Adding to an augmenting path can grow a matching since every other edge in an augmenting path is an edge ...

At the beginning of the 1970s, it was observed that a large class of combinatorial optimization problems defined on graphs could be efficiently solved by non-serial dynamic programming as long as the graph had a bounded dimension, a parameter related to treewidth. Later, several authors independently observed, at the end of the 1980s, that many algorithmic problems that are NP-complete for arbitrary graphs may be solved efficiently by dynamic programming for graphs of bo… into the verse facebook
