1 I know we can enable  Postprocess feasible solutions using an OPS setting file, then in the postprocess block, we can  get the objectives. What I am wondering is can I enable Postprocess feasible solutions using script and how?

2 Is it possible to get these objectives in a main block without using postprocess block?

thanks in advance

Hi,

1) Have you tried thisOplModel.settings.run_processFeasible=true; ?

2) You can do that by either using the solution pools or call the solve with a timelimit, get the solution and call the solve again

Regards

Thank you Alex. I consult the mannual for solution pools, and now I can use getObjValue(i)  to obtain intermidate results, but how to obtain the solving times of these results?  

Why not using var d=new Date();

and then use - to compute times ?

regards

Dear Alex, I can use "var d=new Date();" method to get solve time for each intermediate solutions in the post process block. But I have a large number of instances to solve, so I do not use post process block, instead, I use an independent main file to solve them one bye one.

Now , in the main file, I can use the following code to get intermediate objectives, but, cannot get solve time for e.g. MIP obj 1 , because the solving process have ended. Could you give any idea?
