Abstract

The purpose of this paper is to show that the problem of computing minimum cost index (MCI), which is proposed by Dean and Martin (2010, 2015) as a goodness-of-fit measure of GARP, is NP- hard. We show the result by using a reduction from maximum acyclic subgraph problem (MASP) which is a traditional decision problem known to be NP-complete.
