Last change on this file since 12951 was 12951, checked in by bburlacu, 9 years ago

#1772:

  • Slight refactor in QueryMatch.cs
  • Added a parameter to the genealogy analyzer for removing older generations from the graph (useful to conserve memory in experiments)
  • Updated wildcard nodes (added persistence & cloning)
  • Implemented diversification strategy based on schema frequencies & phenotypic similarity as a separate operator (for now keep also the analyzer)
  • Updated license headers
  • Added QueryMatch performance test (to be expanded)
