Faster Unfolding of General Petri Nets Based on Token Flows
In this paper we propose two new unfolding semantics for general Petri nets combining the concept of prime event structures with the idea of token flows developed in [11]. In contr...

Unfolding Grammars in Adhesive Categories
We generalize the unfolding semantics, previously developed for concrete formalisms such as Petri nets and graph grammars, to the setting of (single pushout) rewriting over adhesiv...

Optimality Properties of Planning Via Petri Net Unfolding: A Formal Analysis
We provide a theoretical analysis of planning via Petri net unfolding, a novel technique for synthesising parallel plans. Parallel plans are generally valued for their execution f...
