info: 'Unknown error (SCIP-linear)

[Saeed.Bagheri]

Dear Johan

I need another help. I had a problem before, that solved with mosek correctly. But, suddenly mosek is crashed and don't work correctly, during the same problem solving. after running, it's show me error: -1 and info: 'Unknown error (SCIP-linear)'.

best regards

All of a sudden? Sure you haven't changed matlab/os/computer/installed something etc

To see what actually happens, run a problem, the shown display says nothing

sdpvar x
optimize(x>=0,x,sdpsettings('solver','scip','debug',1))

I haven't change any things. you say, I reinstall the matlab??

Only mosek solver crashed and for example, CBC works correctly.

[Saeed.Bagheri]

just I installed OPTI-toolbox.

[Saeed.Bagheri]

The mistake was that... OPTI-toolbox.

this toolbox causes the mosek don't work correctly and can't solve the LP problems.

thanks Mr. Johan for your answering.

Best regards

So the claim that nothing was changed was incorrect then

What happens, there should be no problems running opti-toolbox and mosek at the same time

I don't know  what happened when matlab have mosek and OPTI together in same time.
