#3140 assigned enhancement

Add new Symbol <Num>

Reported by: chaider Owned by: gkronber
Priority: medium Milestone: HeuristicLab 3.3.17
Component: Problems.DataAnalysis.Symbolic Version: trunk
Keywords: Cc:

Description

Adding a new Symbol <num> which represents a number value that can be changed. The new Symbol should be used e.g. for the constant optimization so that the constant value will remain constant in future.

r18143 merged branch into trunk

comment:32 Changed 12 months ago by dpiringe

r18144

  • added the StorableAttribute to property Value in symbol Constant, because the ConstantTreeNode references this property and it causes deserialisazion bugs without the attribute

  • adapted symbol Constant and Number for SymbolicDataAnalysisExpressionTreeNativeInterpreter

comment:36 Changed 12 months ago by dpiringe

r18160

  • merged branch into trunk

comment:37 Changed 12 months ago by gkronber

Bugs / suggestion for improvments:

  • values for num are not optimized / changed (tested with paramopt and batchInterpreter)
  • num values cannot be initialized to negative values (<num=-1.5>). Only via workaround: -<num=1.5>. -> fixed in r18169
