#1888:

  • Added a parser for independent scenarios (using the model of the optimization backend)
  • Optimization scenario sample can be found in mappings folder of the web project.
  • Added IScenarioMapper interface which provides functionality to map from the optimization data model to a backend model (e.g. Heuristic Lab data model)
  • Implementations of IScenarioMapper have to be provided as C# code (strings) which will be compiled by using a CSharpCodeProvider. Once compiled, the implementations of the IScenarioMapper are being cached within the platform for further usage.
  • Fixed a bug in web template DecimalMatrix (using i instead of j)
  • Added missing thumprint of localhost certificate to the optimization web project (ServiceConfiguration.Local.cscfg / ServiceConfiguration.Cloud.cscfg)
  • Test project now provides following test cases: Mapping types using IronPython and mapping types using Otis
