Comments

1.	Multiple MINMAX entries are allowed and multiple MAXMIN entries are allowed, but a MAXMIN entry cannot appear in the same input file as a MINMAX entry.

2.	The multiple MINMAX or MAXMIN entries define the same optimization problem.

3.	Refer to Optimization Problem in the User's Guide for more information on "Minmax" optimization.

4.	If the DSYSID entry is referenced by a MINMAX or a MAXMIN subcase entry, the beta method is applied in the optimization as follows:
