Abstract

In this paper, we study an upside-down transformation of a branch in SOL/Connection tableaux and show that SOL/Connection tableaux using the folding-up operation can always accomplish a size-preserving transformation for any branch in any tableau. This fact solves the exponentially-growing size problem caused both by the order- preserving reduction and by an incremental answer computation problem.
