But—practically speaking—Gentzen calculi suffer quite serious disadvantages, unfortunately rendering them unsuitable for use in mechanizing proofs without extensive modification. The primary obstacles to their efficient automation are the nondetermin

In particular, since fair derivation strategies provide means of traversing entire resolution search spaces, in proving the refutation completeness of a given resolution calculus

In this chapter we introduce a notion of . and prove that it is equivalent to that of semantic consequence. The notion of syntactic consequence we will discuss corresponds to an efficiently mechanizable calculus, namely, the . of Gerhard Gentzen.

Introduction,cted a theory of reasoning that endured nearly two thousand years before being developed further by such eminent logicians as Gottlob Frege (1848-1925), George Boole (1815-1864), and Bertrand Russell (1872-1970).
