Description (last modified by abeham)
The algorithm iterator should execute an algorithm instance over and over until a certain stopping criterion is met. The stopping criteria are:
- Maximum execution time reached
- Maximum number of evaluated solutions
- A certain target fitness was achieved
Design issues:
- Algorithm Execution time is hard to obtain (similar problem with the introduction of terminators)
- The precision of execution time from the algorithm is not good enough (~200ms)
- Adding EvaluatedMoves and EvaluatedSolutions is complicated by different cost factors
- Some algorithms/operators count evaluated solution-equivalents instead
- Integer is sometimes too small to hold the amount of evaluated moves for long runs / big problems
- Analyzers depend on BestAverageWorstQualityAnalyzer being run before them
- Arguably, best-so-far quality and execution time are results that the algorithm itself should provide and not an analyzer
- Quality progress chart should be calculated in a separate analyzer
- ISingleObjectiveHeuristicOptimizationProblem specifies MaximizationParameter as an IParameter instead of an IValueParameter<BoolValue>
- Which parameters in a run characterize the algorithm instance?
- E.g. Seed does not characterize the instance
- Analyzers do not characterize the instance, but some "analyzers" may modify penalties
- ResultCollection contains Result objects, but RunCollection.Results contains only the items
- The Result objects are always in the way, they should be removed

comment:6 Changed 20 months ago by abeham
- Description modified (diff)
- Summary changed from Algorithm performance comparison by ECDF to Run-length distribution (RLD) Analysis
comment:7 Changed 20 months ago by abeham
r12803: worked on RLD analysis
- started implementation of IRRRun
- renamed view from ECDF to RLD
- reverted algorithms (execution time)
- changed per clock analyzer
comment:8 Changed 20 months ago by abeham
- worked on IRRestarter (early abort still troublesome)
- Updated RLD view to allow defining targets
- Attempting to handle maximization/minimization
Fun detail:
- HeuristicLab.Analysis references HeuristicLab.Optimization
- HeuristicLab.Optimization.Views references HeuristicLab.Analysis.Views
IRRestarter is currently placed in HeuristicLab.Analysis, its view in HeuristicLab.Optimization.Views.
