The CLP Procedure

Macro Variable _ORCLPEVS_

When you specify the EVALVARSEL= option 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 as follows:


indicates the variable selection strategy being evaluated.


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.


indicates the index of the solution if a solution is found. Otherwise, SOLUTION=NOT_FOUND.


indicates the maximum number of variables selected within the evaluation time.
