Sign of a Linear Expression in Mixed Integer Linear Programming
I have a question about a system in mixed integer programming I am trying to solve using GLPK though the question mathematical and is software agnostic.
I have converted the whole problem to linear equations and inequalities except for one part. Suppose I have a real number and a binary variable (either 0 or 1). How can I "tie them together" such that if and only if ?
