SUMMARY OF CHANGES IN RIVERWARE PATCH RELEASE 8.5.1 Released July 26, 2022 Optimization Restore Points ---------------------- Optimization Restore Points allow an optimization problem to be saved at an intermediate point. A subsequent run can then use that saved state as an advanced start. Restore Points were refined in the following manner. - An improvement was made to the handling of constraints that shrink to higher priority constraints of the same form. - The precision used for RPL unit conversion factors in Restore Points was increased. - A problem was addressed in the handling of slot variable bounds. These improvements were made to guarantee that the restored optimization problem matches the state of the problem when the Restore Point was created. These changes only affect optimization models that use a Restore Point. Set Optimization Parameter script action ---------------------- The action previously called "Set Optimization Integer Parameter" has been generalized so that it can now set parameters that are real numbers (doubles). It has been renamed "Set Optimization Parameter". This change will not impact existing scripts. Issues ---------------------- The following issues were addressed: 6743: Generating an optimization log file when using an Optimization Restore Point issued an error. 6752: Applying a Window Layout led to an incorrect error notification. 6753: The Model Comparison Tool incorrectly reported differences for multiple items with the same name. 6755: Closing the scalar slot viewer after deleting a scalar slot caused a crash. -- [end] --
