How to import node file(cpx~) for initialzing solution?

Post by leewing159 » 1 week ago

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
