How to import node file(cpx~) for initialzing solution?
Posted: Tue Nov 22, 2022 11:29 am
Hi,
The gams(CPLEX) was solving a MILP problem for a week, generating tons of cpx file.
(I guess this is cplex nodefile from cplex option nodefileind 2.)
(All the files name starts from cpx****** (example, cpx494734).)
Suddenly, the gams studio failed (when I zoom in with "ctrl+wheel scroll"), as a results, the programming aborted. (so sad...)
Is there any way to start the code over with the last state of the problem?
The program had been running for 5~6 days, and I do not want to start it agrain from the beginning.
Please help me out, if you know something... (the below fig is gamsstat.dat)
Best Regards,
Wonjong Lee
