Abstract:

Geetha and Nair recently proposed a variant of n × n assignment problem with the objective of minimizing the total cost plus an additional ‘supervisory’ cost. They gave an O(n5) algorithm to solve the problem. Here, we present an algorithm for this problem using Balinski's signature method for the assignment problem at each stage. The algorithm has a complexity of O(m(m+n log n)), where m is the number of arcs in the problem.
