Abstract
This thesis describes a decision and minimization procedure for modal logic. The decision procedure answers the question of whether there exists a satisfying pointed model for a formula which obeys user-specified first-order conditions on the underlying frame. Then the minimization procedure produces a minimal model with respect to the number of worlds that satisfies the desired formula while obeying the requisite conditions on the underlying frame. A proof of correctness for the decision and minimization procedures is supplied, as well as a description of an implementation built upon the Enfragmo model expansion solver.
