MILP problems from miplib sorted according to mps file size. Results
obtained with lp_solve 1.4 on a 44 MFLOPS HP9000/735.

lp_solve employs a rather simple branch-and-bound scheme to solve MILP
problems and should not be expected to solve problems with a very large number
(>100) of integer variables in reasonable time.

Example, rows, cols, nonzero, integer and binary columns should be clear.

OK result indicates that I have obtained the same result as indicated as
correct. - indicates no result obtained.

The remarks column indicates how or why not a result was obtained. Several
examples need the -e 0.01 option to avoid looping and stack overflow.

I have not yet tried the other (larger) examples, but they could take quite
some time...
