      Trac #26994: graph canonical labels and doctest failures in databases/sql_db.py · bc5178a8
      Release Manager authored
      Starting from somewhere around 8.5.beta the canonical labels given by
      Sage and bliss are different on some instances
      {{{
      sage: G1 = Graph("Cr")
      sage: G2 = Graph("C]")
      sage: G1 == G2
      False
      sage: G1.is_isomorphic(G2) and G2.is_isomorphic(G1)
      True
      sage: G1.canonical_label(algorithm='bliss') == G1
      True
      sage: G1.canonical_label(algorithm='sage') == G2
      True
      }}}
      That is `Cr` is canonical for bliss while `C]` is canonical for Sage...
      More examples:
      - 4 vertices: {{{C`}}} vs {{{CK}}}, {{{CR}}} vs {{{CL}}} and {{{Cr}}} vs
      {{{C]}}}
      - 5 vertices: {{{DGC}}} vs {{{D@O}}}, {{{DAK}}} vs {{{D@S}}}, {{{DC[}}}
      vs {{{D@s}}}, {{{DIK}}} vs {{{DBW}}}, {{{DD[}}} vs {{{DBk}}}, {{{DDW}}}
      vs {{{DBg}}}, {{{D`{}}} vs {{{DK{}}}, {{{DqK}}} vs {{{DLo}}}, {{{DMk}}}
      vs {{{Dbk}}}, {{{DR{}}} vs {{{DL{}}}, {{{DR[}}} vs {{{DJk}}}, {{{Dr{}}}
      vs {{{D]{}}}
      
      As a consequence, when bliss is installed, we have the two following
      doctest failures in `databases/sql_db.py`.

      Release Manager authored
      Trac #26676: Fix var() method for cryptominisat and picosat, which breaks solve_sat for boolean polynomial systems
      
      When I used Sage7.2, I could easily solve my boolean equations with
      solve_sat commands, and it's results were verified by the papers and
      other tools, but when I upgraded my sage to version 8 (or later version)
      I found that the new solve_sat solver (especially when we use
      CryptoMiniSat as the SAT solver) doesn't work as correct as before. For
      example, when I solve a system of equations via solve_sat which used
      CryptoMiniSat as a SAT solver, I get different number of solutions in
      different version of SageMath. I believe that there is something wrong
      in newer version of SageMath because my previous experiences shows that
      the older version's results were verified by the other tools and papers.
      I hope someone could solve this problem.
