Release Notes : Prior Release Notes (Versions 1.0 to 9.3) : What’s New in Version 9.3 : Optimization
Optimization
The following changes were made to Optimization.
Default LP Method
The default value for the LPMETHOD CPLEX parameter was changed from “Automatic: Let CPLEX Choose” to “Primal Simplex”. Effectively, this was already the setting; if “Automatic: Let CPLEX Choose” was selected, at the start of the run, RiverWare would switch the method to Primal Simplex and issue a warning.
With this change, RiverWare no longer issues the warning unless the user has manually changed the LPMETHOD CPLEX back to “Automatic: Let CPLEX Choose”.
