RESET Statement
- RESET options ;
The RESET statement is used to change options after the LP procedure
has started execution.
All of the options that can be set in the
PROC LP statement can also be reset with the RESET statement,
except for the DATA=, the PRIMALIN=, and the ACTIVEIN= options.
In addition to the options available with the PROC LP statement,
the following two options can be used.
- LOWER(colnames)=n;
-
during phase 3, this sets the lower bound on all of the
structural variables listed in the colnames list to
an integer value n. This may contaminate the branch and bound tree.
All nodes that descend from the current problem have lower
bounds that may be different from those input in the problem
data set.
- UPPER(colnames)=n;
-
during phase 3, this sets the upper bound on all of the
structural variables listed in the colnames list to
an integer value n. This may contaminate the branch and bound tree.
All nodes that descend from the current problem have upper
bounds that may be different from those input in the problem
data set.
