| - | ===== How do I create a report with some technical information about the optimzation? ===== | ||
| - | You can save the solver status and model status along with the objective value. This also works for solves in a loop. Below is an example: | ||
| - | <code> | ||
| - | parameter report (*,*); | ||
| - | |||
| - | loop {I, | ||
| - | solve m using nlp min z; | ||
| - | report(I,'objval') = m.objval; | ||
| - | report(I,'modelstat') = m.modelstat; | ||
| - | report(I,'solvestat') = m.solvestat; | ||
| - | }; | ||
| - | </code> | ||
| - | There's plenty more one could include. To get a list, just make a mis-spelling of one of the model suffices - this provokes GAMS/Base into giving you a list of the allowed ones: | ||
| - | <code> | ||
| - | 2. set by gams after each solve execution | ||
| - | domusd, etalg, etsolve, etsolver, handle, iterusd, line | ||
| - | linkused, modelstat, nodusd, number, numdepnd, numdvar | ||
| - | numequ, numinfes, numnlins, numnlnz, numnopt, numnz | ||
| - | numredef, numvar, numvarproj, objest, objval, procused | ||
| - | resgen, resusd, robj, solvestat, suminfes | ||
| - | </code> | ||
| - | |||
| - | You may also use a [[interfaces:send_model_status_to_a_gdx_file|gdx file to store this information]]. | ||
