FICO Decision Optimizer 8.3.3 – April 2021

New Functionality and Changes Introduced with Decision Optimizer 8.3.3 
This release is a maintenance release, with a few enhancements and resolution of some defects.  

Added in Decision Optimizer 8.3.3 

Performance improvement 

Decision Impact Model Execution 

• Improvements in the decomposition of execution steps have reduced peak memory usage, which in turn has reduced scenario run times. 

Tree Aware Optimization 

• Improvements in the logic used to generate consistency constraints for some tree template over base trees have drastically reduced scenario run times. 

General Optimization 

• Ability to use the Xpress Optimizer concurrent solvers, leveraging as many threads as allowed by the Xpress Insight Execution Service. 

Display execution time 

• Added the execution time for each component in the run log 

Decision Table Editors (these additional features are only available, if upgrading to Xpress Insight 4.56) 

• Ability to plot a simple string column as an unscaled x axis      

• Ability to drag a point to change the curvature of the whole line      

• Ability to straighten and smooth a line      

• Precision rounding, when manipulating data point(s) 

Authority Roles / Project Access (Beta) 

• To enable better project control/access, users have the ability to use/define different authority roles (e.g. project analyst, strategy analyst, approver, IT manager) and define different levels of project access (e.g. read-only, full access). This initial release is considered Beta functionality to allow wider testing, before full release. 

Defect Remediation 

Several user reported and internally discovered defects have been fixed, including: 

• Swap set report  (fixed in DO 8.3.1) 

• Tree Aware Optimization omits some leaf node consistency pairs when optimizing a base tree  (fixed in DO 8.3.2) 

Documentation 

Improvements have been made in sections of the Analyst User Guide covering:  

• Improved guidance on how to set rank consistencies for Tree Aware Optimization  

• Added clarification for the “Account Constraints” table in Summary report. 

• Added clarification on the delta metric. 

Miscellaneous: 

• For users already on DO 8.3.x, there is no need to upgrade Xpress (8.11) or Xpress Insight (4.55), with the caveat that if you want the incremental Decision Table Editor enhancements, you will need to upgrade Xpress Insight to 4.56.
