| Macro Variable _ORCLPEVS_ |
When the EVALVARSEL= option is enabled in order to evaluate variable selection strategies for a nonscheduling problem, the CLP procedure defines a macro variable named _ORCLPEVS_. 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.
- VARSELTYPE
indicates the variable selection strategy being evaluated.
- EVAL_TIME
indicates the amount of time taken to evaluate the variable selection strategy. By default, the time reported is CPU time; see the TIMETYPE= option for more information.
- SOLUTION
indicates the index of the solution if a solution is found. Otherwise, the value NOT_FOUND appears.
- MAX_VARSEL
indicates the maximum number of variables selected within the evaluation time.
