The CLP Procedure

Macro Variable _ORCLPEAS_

When you specify the EVALACTSEL= option 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 that a solution has been found. Otherwise, SOLUTION=NOT_FOUND.

REASON: indicates the reason a solution was not found. The reason can be either TIME_LIMIT_REACHED or RESTART_LIMIT_REACHED. This term is included only when SOLUTION=NOT_FOUND.

MAX_ACTSEL: indicates the maximum number of activities selected within the evaluation time.
