Dear Sir or Madam, I am writing my master's thesis and therefore I am using the GLPK with exact arithmetic for large problems with 995 rows and 558 columns/variables. My problem has 372 variables which have to be between 0 or 1. I use the GLPK during my implemented Branch and Bound algorithm to solve the LP-relaxed subproblems. At some point I fixed about 30 variables to 0 or 1 and then the solver loops infinitely on that data set. Do you know something about such an bug?
