object ModelSearchProver
A prover that tries to construct a countermodel of a ground formula. This
prover works in depth-first mode, in contrast to the
ExhaustiveProver

are the formulae (connected disjunctively) to be disproven. The result of the method is either countermodel ofinputDisjuncts
(the caseLeft
), or a proof of validity (Right
). In case proof construction is disabled, the validity result will beLeft(FALSE)

is the formula to be disproven. The result of the method is a countermodel ofinputFor
