| Macro Variable _ORCLPEAS_ |
When the EVALACTSEL= option is enabled in order to evaluate activity selection strategies for a scheduling problem, the CLP procedure defines a macro variable named _ORCLPEAS_. This variable contains a character string that describes the solution attempt made with each selection strategy. The macro variable contains four terms for each selection strategy that is evaluated; these terms are interpreted as follows.
- ACTSELTYPE
indicates the activity selection strategy being evaluated.
- EVAL_TIME
indicates the amount of time taken to evaluate the activity selection strategy. By default, the time reported is CPU time; see the TIMETYPE= option for more information.
- SOLUTION
indicates the index of the solution in the output data set, provided a solution has been found. Otherwise, the value NOT_FOUND appears, followed by the reason a solution was not found (either TIME_LIMIT_REACHED or RESTART_LIMIT_REACHED).
- MAX_ACTSEL
indicates the maximum number of activities selected within the evaluation time.
