Different propositional proof systems for propositional logic, such as the sequent calculus, the cutting-plane method, resolution, etc., may provide different proofs for the same complexity measures the efficiency of the proof system usually in terms of the minimal size of proofs possible in the system for a given tautology (or dually, and unsatisfiable.

Random forcing can be defined as forcing over the set of all compact subsets of [,] of positive measure ordered by relation ⊆ (smaller set in context of inclusion is smaller set in ordering and represents condition with more information).
