Dear Andrew, I just added a limit on the number of restarts in the simplex algorithm. In this way i do avoid the infinite loop. Could it be officially supported?
It would be nice to have a function that makes a hexadecimal snapshot of the internal state of the solver and writes it to the disk so it can be reproduced. Could you please help me how my LP problems should be change to improve their numerical properties? I already removed the tiny coefficients as you proposed and i suspect now the tiny row bounds are causing the trouble. An example is at the link i sent yesterday. The main.cpp takes the dump.txt as the input, builds the problem, writes it as dump.lp then starts the iteration and produces the log.txt console output. I can only reproduce this in the Windows environment. Many thanks for your help, Ali _______________________________________________ Bug-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-glpk
