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.
