Abstract :
In Toroslu and Üçoluk [I.H. Toroslu, G. Üçoluk, Incremental assignment problem, Information Sciences 177 (2007) 1523–1529] the incremental assignment problem is defined as follows. A new pair of vertices and their incident edges are added to a weighted bipartite graph whose maximum-weighted matching is already known, and the maximum-weighted matching of the extended graph is sought. An O(n2) algorithm for the problem has been derived, with n the size of a partition in the bipartite graph. We point out that such a result can be found in literature.
