Greetings,
My model works for a number of instances except for a large instance(~
400000 vars and 200000 cons) on which I am getting this error:
---
Presolve eliminates 34074 constraints and 34074 variables.
...
Error at _cmdno 71 executing "solve" command
(file model.run, line 62, offset 1585):
can't open model.sol
---
I suspect that cplex is dying at some point. In order to trace the
problem I'd like to get more information from cplex along its
progress. What options can I use for troubleshooting cplex?
Thank you, \\Guney
