  • Abstract
    Model checking of 3-valued logical formulae is analyzed. The solution is presented when the value of model checking for a 3-valued logical formula is UNKNOWN. In this paper, a proof system is established on a 3-valued logic, with additional proof steps, by which the approaches of extracting witness (counter-example) when the result on checking a formula with existential (universal) path quantifier is UNKNOWN are obtained. The direction of refinement in a partial Kripke structure is given by witnesses and counter-examples.
