Structure-template GP Exception: Numeric Parameters cannot be found in the provided scope. #3183

Closed gkronber closed 1 year ago

gkronber commented 1 year ago

Describe the bug An exception is raised when trying to run structure-template GP without linear scaling.

HeuristicLab version: 3.3.16.8896
OperatorExecutionException: An exception was thrown by the operator "Single-objective Evaluator" [C:\Users\Gabriel\Downloads\HeuristicLab trunk\HeuristicLab.Optimization-3.3.dll: 3.3.16.8896]:  Numeric Parameters cannot be found in the provided scope.

To Reproduce Steps to reproduce the behavior:

  1. Open "Genetic Programming - Structure Template" Sample
  2. Open "Structure Template" parameter and disable linear scaling checkbox.
  3. Start algorithm
  4. See error

Expected behavior Should work with and without linear scaling
