#2855 readytorelease defect

Showing the encoding or its operators in the run is highly wasteful

Reported by: abeham Owned by: gkronber
Priority: medium Milestone: HeuristicLab 3.3.16
Component: Optimization Version:
Keywords: Cc:

Description

Runs generated by solving a BasicProblem are typically larger than those that solve a HeuristicOptimizationProblem. BasicProblems define an Encoding which usually contains several operators. The Encoding and its operators are added to the parameters of each run which in turn creates a noticeable memory overhead (especially for larger experiments). Similar optimizations have been performed in the past, that e.g. operators in the run are stored only by their name (StringValue) instead of by their full type.

r16860: Reduced footprint of encoding in run

  • Instead of the encoding instance, only its name is added to the run (necessary to change in BasicProblem)
  • By default the operators parameter of an encoding is set to not be collected (change in Encoding)

  • Status changed from reviewing to readytorelease

I reviewed r16860 and found no problems.
