Re: [Help-glpk] Maximum number of integer variables

It is a benchmark for the miplib, a set of mip instances, showing
the performance of the glpk mip solver.

For example, the line

dsbmip   -3.051981750e+02              opt      233   3283      9    2.8

says that mip instance 'dsbmip' was solved to optimality for about
9 secs. In the second table you can find characteristics of that
instance:

dsbmip     1855   1886 (   192    160)   9768         -305.198 (opt)

that means that 'dsbmip' has 1886 variables, 192 of which are integer,
and 160 of 192 integer variables are binary.
