Introduction Prover9 is a resolution/paramodulation automated theorem prover for first-order and equational logic. Prover9 has a fully automatic mode in which the user simply gives it formulas representing the problem and obtain the proof process.

Input Format Use the symbols in the left side to substitute the ones in the right side. When in doubt, include parentheses. Each formula ends up with ‘.’
