Trying to debug a stack error in GLPK, I am writing the problem out at
every iteration of a column generation scheme
Initially only in the free mps format, but then also in the lp format
One major and one minor error occur:
major: write_freemps does not write the objective function coefficients,
no column has a non-zero in the objective function
minor: write_cpxlp creates one extra variable in the bounds section that
does not appear anywhere else in the problem statement
I have attached two files that are written at the same time in the
algorithm (iteration 2), they illustrate the errors
