FPRD-RDV-D01

Reversible reachability with data

Exact statement

A reversible data VASS uses finitely many place types and orbit-finitely many multiset-rewrite rules over a data domain; every rule is available in both directions, and reachability asks whether one finite marking rewrites to another.

StatusPrecisely stated with reversibility and effectiveness separated
External reviewNo documented external or specialist review of this FPRD exposition is recorded.

Context

The symmetry of the rewrite relation is essential: polynomial ideals forget direction.

Definitions

  • A marking is a finite multiset of pairs (data value, place).
  • Orbit-finite rules are represented by finitely many rule orbits under data renaming.

Hypotheses and scope

  • The data domain is homogeneous when embeddings on finite supports are replaced by automorphisms.
  • Algorithmic claims additionally need an effective representation of orbits and embeddings.

Proof or evidence

This model is the common interface between reversible data Petri nets and equivariant binomial ideals.

Verification notes

Reversibility, homogeneity, orbit-finiteness, and effectiveness were recorded as separate requirements.

Limitations

  • Abstract homogeneity and WQO assumptions alone do not specify an algorithm.
