Mixed-Integer Programming to Solve Distribution Problems
Journal of New Results in Science, 2020 Mixed-integer linear and quadratic programming problems are considered to solve distribution problems in this paper. The first problem is the distribution of proctors with respect to the student placements to the class- rooms by mixed-integer linear ...

Projected Chvátal–Gomory cuts for mixed integer linear programs [PDF]
Mathematical Programming, 2006 Recent experiments by Fischetti and Lodi show that the first Chvátal closure of a pure integer linear program (ILP) often gives a surprisingly tight approximation of the integer hull. They optimize over the first Chvátal closure by modeling the Chvátal–Gomory (CG) separation problem as a mixed integer linear program (MILP) which is then solved by a ...
