Changeset 12035

#2269

  • Added LayerUniformSubScopesProcessor which introduces an intermediate ExecutionContext which translates array-based parameters to single-value parameters.
  • Updated ALPS-OperatorGraph to make usage of the new LayerUniformSubScopesProcessor.
  • Added a temporary operator for calculating number of selected sub scopes because presetting the value during operator parameterization does not work for the new intermediate context.

Note: the change of the PopulationSizeParameter still causes an error when creating a new layer. This will be fixed soon.
