[Cmpl] Ynt: Gurobi solver error

[Duygu Bedir]

Hi,


Thank you for the quick reply. You can find the model and the csv used in the attachments.


It seems to be working fine with the Cbc and finds a feasible result, but in the future we need to use the same model with a nearly 200*200 matrix so we need Gurobi to work also.


Also, I tried to delete and setup the Cmpl into different folder. The model gave the same error, but now the first location in the error is the location of my new Cmpl folder.



CMPL model generation - running


CMPL version: 1.12.0

Authors: Thomas Schleiff, Mike Steglich

Distributed under the GPLv3


create model instance ...

write model instance ...


CMPL model generation - finished


Solver - running


"C:/Users/duygu/Cmpl" "0" "C:/Users/duygu/AppData/Local/Temp/cmpl.gq9696.mps" "C:/Users/duygu/AppData/Local/Temp/cmpl.gq9696.gsol"


The system cannot find the path specified.


Error (interfaces): gurobi failed - exit code 



Thanks again,
Duygu

Konu: Re: [Cmpl] Gurobi solver error

Hello,

Could you please try to solve it with Cbc? Just to check whether there is a feasible solution. You could also send your Cmpl model directly to me to test it on my system.

Thanks,

Mike
