    Hi, 

     

    How to avoid the initialization of the tuples resultats in post-processing during the model running in Docloud ? 

     

    I wish the tuple resultats of a solution start initialization only if the model finish its running.

    It takes times and doesn't seem to bring any interesting information in the resolution. Someone can help please ?

     

    example :

    You may disable the execution of post-processing on intermediate solutions by adding the following setting in the opl model: execute{ settings.oaas_processFeasible = 0; } 

    Please try it.
