WebAn integer programming problem in which all variables are required to be integer is called a pure integer pro-gramming problem. If some variables are restricted to be integer and some are not then the problem is a mixed integer programming problem.Thecase where the integer variables are restricted to be 0 or 1 comes up surprising often. WebThe variables b u v equals 1 if the edge ( u, v) is cut. We want to enforce the following constraints: a s = 0 and a t = 1. b u v = 1 if a u = 1 and a v = 0 or if a u = 0 and a v = 1. ∑ u v ∈ E w ( u, v) b u v ≤ k. Try to encode all these constraints as inequality constraints. Share Cite answered Jan 3, 2016 at 20:52 Yuval Filmus 273k 26 301 493
