The 3x+1 Problem as a String Rewriting System

WebEvery Post canonical system can be reduced to a string rewriting system (semi-Thue system). It has been proved that any Post canonical system is reducible to such a substitution system, which, as a formal grammar, is also called a phrase-structure grammar, or a type-0 grammar in the Chomsky hierarchy.

WebWhat you've described is an instance of a string rewriting system, also known as a semi-Thue system. Start with a finite alphabet, Σ, and a binary relation, R, on strings over Σ. For your example, we'll have R defined by. We can then define another relation, ⇒, on strings by, basically, applying R to substrings.

In the present paper, we transfer this result to match-bounded string rewriting. Every match-bounded system terminates, and eﬀectively preserves regularity of lan-guages.

String rewriting system

In theoretical computer science and mathematical logic a string rewriting system (SRS), historically called a semi-Thue system, is a rewriting system over strings from a (usually finite) alphabet. Given a binary relation between fixed strings over the alphabet, called rewrite rules, denoted by , an SRS extends the rewriting relation to all strings in which the left- and right-hand side of the rules appear as substrings, that is , where , , , and are strings. WebIn string rewriting system, does rewriting 'consume' the string? For instance, suppose 101 is written down and there's a rule 1 x 1 → 11 x 11, we can apply this rule to write down 11011, but do we have to cross off 101? logic formal-systems Share Cite Follow edited Aug 16, 2013 at 9:46 asked Aug 16, 2013 at 9:33 goblin GONE 65.9k 16 94 268

WebOct 14, 2004 · In a match-bounded system, match heights are globally bounded. Using recent results on deleting systems, we prove that rewriting by a match-bounded system preserves regular languages. Hence it is decidable whether a given rewriting system has a given match bound. We also provide a criterion for the absence of a match-bound.

Webrewriting system because they rewrite rewriting paths. The idea is quite appealing, but it is not clear at rst how the classical rewriting frame-works should t in this picture, and one should rst try to understand in a uniform way the two major examples of rewriting theory: string rewriting systems and term rewriting sys-tems.

Weba reduction. A string rewriting system is called match-bounded if there is an upper bound to these numbers.
