deductive tableau
deductive tableau
(tool)A theorem proof system consisting of a table whose rows
contain assertions or goals. Variables in assertions are
implicitly universally quantified and variables in goals are
implicitly existentially quantified. The declarative meaning
of a tableau is that if every instance of every assertion is
true then some instance of at least one of the goals is true.
