#2701:

  • Updated LLE encoding
    • Made folder for version 3.4
    • Added conversion from and to LLE-b representation (back-links)
    • Updated moves and movegenerator to replace bidirectionaldictionary with LLE-b representation
  • Updated MemPR (linear linkage)
    • Updated tabu walk
  • Added test for conversion between LLE-e and LLE and LLE-b and LLE
  • Updated test for move apply/undo and added test for applying in sequence
