An induced matching in a graph is a matching such that no two edges are joined by an edge of G. For a connected graph G, denote by iμ(G) the maximum cardinality of an induced matching in G. In this paper we study the proble of finding a maximum induced matching in grid graphs with n lines and m columns—G n, m , and determine the exact value for iμ(G n, m ) when n or m are even.



I would like to thank Marc Demange from ESSEC Business School for suggesting me this problem and for his support.
