Dear all,
Once again I need some help with TRNSYS/TRNOPT.
I am trying to do an optimization with the "hybrid for continuous and discrete variables (VonNeumann)" algorithm which contains the particle swarm optimization and the hooke-jeeves. However, when doing the optimization I get an I/O error 32 (see attached screenshots) and the following:
Simulation 21: Caught 'genopt.lang.OptimizerException' with message: File: 'C:\Trnsys17\Optimization\GenOpt\Simulation\tmp-genopt-run-21\GenoptInputFile.LST' does not exist after simulation call.
Simulation working directory : 'C:\Trnsys17\Optimization\GenOpt\Simulation\tmp-genopt-run-21'
Command string : 'C:\Trnsys17\Exe\TRNExe.exe "C:\Trnsys17\Optimization\GenOpt\Simulation\tmp-genopt-run-21\GenoptInputFile.DCK" /h /WAIT '
Try to evaluate simulation a second time.
When I close the error the optimization continues again and after doing this two or three times it eventually finds the minimum of the cost function. Does anyone know what this error could be and how to solve it? Otherwise I can't be sure how correct the results are ofcourse. Or could be have to do with the random particles chosen by the algorithm and some of them falling outside the boundaries?
Any help is appreciated. Thanks.
Kind regards,
Michel
