The OPTMODEL Procedure

RESTORE Statement

RESTORE identifier-expression;

The RESTORE statement adds a constraint, constraint array, or constraint array location that was dropped by the DROP statement back into the solver model. Identifier-expression specifies the constraint. An entire constraint array is restored if the identifier-expression omits the index from an array name. For example, the following code declares a constraint array and then drops it:

  
    con c{i in 1..4}: x[i] + y[i] <=1; 
    drop c;
 

The following statement restores the first constraint:

  
    restore c[1];
 

Multiple names can be specified in a single RESTORE statement. The following statement restores the second and third constraints:

  
    restore c[2] c[3];
 

If you want to restore all of them, you can submit the following statement:

  
    restore c;
