#16 closed enhancement (rejected)

Implement analysis of variable infos to identify invalid data dependencies

Reported by: swagner Owned by: swagner
Priority: lowest Milestone: HeuristicLab 3.3.0
Component: Core Version: 3.2
Keywords: Cc:

Description

Variable infos provide information about the variables an operator creates, reads, writes, etc. This information could be used to statically analyze operator graphs to find invalid data dependencies and to inform the user about it.

Additionally this analysis would be crutial for GP-based development of heuristic optimization algorithms to identify invalid solutions.

  • Resolution set to wontfix
  • Status changed from new to closed

VariableInfos have been replaced by Parameters in HeuristicLab 3.3. Anyhow, a comprehensive analysis of data dependencies is very hard, as it would not only require a static analysis but also an analysis of the dynamic behavior of an algorithm. The cost-benefit ratio of this enhancement is rather questionable and therefore this ticket will not be addressed in the future.
