> To check the package on the target platform try './glpsol --mps plan.mps'.
Hi Andrew,
Thanx for the assistance. Unfortunately, the results from the source and
target platforms differed significantly. Here is the result from my linux
PowerPC 440EPx target:
lpx_read_mps: reading problem data from `plan.mps'...
lpx_read_mps: problem PLAN
lpx_read_mps: 8 rows, 7 columns, 48 non-zeros
lpx_read_mps: 54 cards were read
glp_simplex: original LP has 8 rows, 7 columns, 48 non-zeros
PROBLEM HAS NO PRIMAL FEASIBLE SOLUTION
Time used: 0.0 secs
Memory used: 0.0 Mb ((null) bytes)
I repeated the same on the Windows/Cygwin source PC:
lpx_read_mps: reading problem data from `plan.mps'...
lpx_read_mps: problem PLAN
lpx_read_mps: 8 rows, 7 columns, 48 non-zeros
lpx_read_mps: 54 cards were read
glp_simplex: original LP has 8 rows, 7 columns, 48 non-zeros
glp_simplex: presolved LP has 7 rows, 7 columns, 41 non-zeros
lpx_adv_basis: size of triangular part = 7
0: objval = 6.500000000e+02 infeas = 1.000000000e+00 (0)
2: objval = 4.376770833e+02 infeas = 0.000000000e+00 (0)
* 2: objval = 4.376770833e+02 infeas = 0.000000000e+00 (0)
* 8: objval = 2.962166065e+02 infeas = 0.000000000e+00 (0)
OPTIMAL SOLUTION FOUND
Time used: 0.0 secs
Memory used: 0.1 Mb (54416 bytes)
The point of departure between the two appears to be during/immediately after
the presolve step. Hopefully one of them is correct, presumably the PC! Not
sure if this provides enough information on what to try next?
Seasons greetings,
Orlan Franks
