Hello, I've been trying different solvers for my mixed integer programming problems. For a specific problem (LP file: http://pastebin.com/3tih0fqg), I get a INTEGER UNDEFINED status with GLPK. However, I believe the correct status should be no integer feasible solution which is what I get when I use CBC from COIN-OR.
The solution output file for this problem is: Problem: Rows: 47 Columns: 1345 (1344 integer, 1344 binary) Non-zeros: 1633 Status: INTEGER UNDEFINED Objective: OBJ = 0 (MINimum) Any clue as to why GLPK is returning an undefined status instead of an infeasible one for this problem? I'm using GLPK version 4.52.1 . I've also got the output from it (http://pastebin.com/ysQiktir).
