New Functionality and Changes Introduced with Decision Optimizer 8.7
New Features and Changes
  • In exploration scenario, warm start solutions are now used and repaired by the solver.This can speed up execution times on non-trivial problems, where it is difficult to find an initial feasible solution for each explored point.
  • Improved time to process consistency constraints reporting for scenarios with very large consistency constraint segment sets
Defect Remediation
  • Limited number of decimals for swap set reports
  • Added documentation for the %Difference values in the Global Constraints table of Summary Reports
  • Tree Aware Optimization (TAO) works as expected when using a tree template with base tree in FJDT format
Additionally, the Action Effect Modeling v1.2 releasefocuses on improved performance and including key requested features.
New Features and Changes
  • Introduced scoring mechanism for additional (out-of-time) dataset
  • Improvements in Base Model and Action-Effect Model has reduced run times by 70-90% in benchmark projects.
  • Simpler and more efficient mosel code in generated eqn file
  • Binning: 
  • last bin with infinity upper bound is always part of the binning
  • user can select if the bound of a bin is inclusive or not, independently for each bin
  • "Import binning" now only imports user set breakpoints, without automatically applying them
  • for predictor binning, added delta values to the Fitted and Observed Sensitivity charts and a new Sensitivity Delta chart
Defect Remediation
  • When executing Base Model training, most AE model options are preserved and not cleared
  • Cleanup of old data when a new input file is loaded or variable roles are changed
  • Fixed possibly invalid generated names for exported files and variable names when the scenario name contains blanks and/or special characters
  • Removed “run” option from the scenario dropdown menu
  • Removedpartial recount in the “Import Binning Config”. Now working as expected
Note: This release requires users to upgrade to Xpress 9 and Xpress Insight 4.59.2.
