miplib_results

亚定方程组求解：If serial correlation is found, you may have misspecified your model and should return to y

MILP problems from miplib sorted according to mps file size. Results
obtained with lp_solve 2.0 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 a result was obtained, or why lp_solve failed.
