efficiency mode

size: A proof that uses less axioms is better generally;

  • A(1,2,3,4) > B(2,3,4,5,6)

partial order: A proof that uses a subset of the axiom of another is better than that other; (unless there is a subset relation)

  • A(1,2) > B(1,2,3,4,5,6)

discovery mode

uniqueness: A proof that is further away from (all other known proofs) is better.

  • C(1,5,6), A(1,2,3), B(1,2,4), C is better than A or B given A,B,C

    • lowest average axiom frequency
