A general purpose exact solution method for mixed integer concave minimization problems (revised as on 12/08/2021)
Sinha, Ankur; Das, Arka; Anand, Guneshwar; Jayaswal, Sachin (Indian Institute of Management Ahmedabad, 2021-03-01)In this article, we discuss an exact algorithm for mixed integer concave minimization problems. A piece wise inner-approximation of the concave function is achieved using an auxiliary linear program that leads to a bilevel ...
