############################################################################## # This file contains some example formulas to try # ############################################################################## # A simple propositional test (~r → p) & (r → q) -> (p | q) # The Application axiom should derive instantly in both j0-new and j0-ghari x:A → y:(A → B) -> y*x:B # ... and this one should fail instantly x:A → y:(A → B) -> x*y:B # This is a good one: it works in both j0-new and j0-ghari, but inspects about # 18000 formulas in the latter (or 8000 if x:A is in the CS instead of the # antecedent) x:A → y:(A → B) → y*(x+x'):B # ... And this one just gets too complex to find at all x:A → y:(A → B) → (y+y')*x:B
