A term-rewriting characterization of PSPACE
نویسنده
چکیده
Isabel Oitavem has introduced a term rewriting system (TRS) which captures the class FPS of polynomial-space computable functions. We propose an alternative TRS for FPS. As a consequence, it is obtained that FPS is the smallest class containing certain initial functions and closed under specific operations. It turns out that our characterization is relatively simple and suggests an uniform approach to the space-complexity.

An Implicit Characterization of the Polynomial-Time Decidable Sets by Cons-Free Rewriting
We define the class of constrained cons-free rewriting systems and show that this class characterizes P , the set of languages decidable in polynomial time on a deterministic Turing machine. The main novelty of the characterization is that it allows very liberal properties of term rewriting, in particular non-deterministic evaluation: no reduction strategy is enforced, and systems are allowed t...
متن کاملA characterization of polynomial complexity classes using dependency pairs
The dependency pair method has already shown its power in proving termination of term rewriting systems. We adapt this framework using polynomial assignments in order to characterize with two distinct criteria the set of the functions computable in polynomial time and the set of the functions computable in polynomial space. To our knowledge, this is a first attempt to capture complexity classes...
متن کاملControlled Term Rewriting
Motivated by the problem of verification of imperative tree transformation programs, we study the combination, called controlled term rewriting systems (CntTRS), of term rewriting rules with constraints selecting the possible rewrite positions. These constraints are specified, for each rewrite rule, by a selection automaton which defines a set of positions in a term based on tree automata compu...
متن کاملCongruence Closure of Compressed Terms in Polynomial Time
The word-problem for a finite set of equational axioms between ground terms is the question whether for terms s, t the equation s = t is a consequence. We consider this problem under grammar based compression of terms, in particular compression with singleton tree grammars (STGs) and with directed acyclic graphs (DAGs) as a special case. We show that given a DAG-compressed ground and reduced te...
متن کاملTermination of Rewriting with Right-Flat Rules Modulo Permutative Theories
We present decidability results for termination of classes of term rewriting systems modulo permutative theories. Termination and innermost termination modulo permutative theories are shown to be decidable for term rewrite systems (TRS) whose right-hand side terms are restricted to be shallow (variables occur at depth at most one) and linear (each variable occurs at most once). Innermost termin...
