Adjunct Hexagonal Array Token Petri Net Structures (AHPN) are recently introduced hexagonal picture generating devices which extended the Hexagonal Array Token Petri Net Structures . In this paper we consider AHPN model along with a control feature called inhibitor arcs and compare it with some expressive hexagonal picture generating and recognizing models(More)
Adjunct Array Token Petri Net Structures (AATPNS) are recently introduced rectangular picture generating devices which extended the Array token Petri net Structures. AATPNS generated context free and context sensitive kolam array languages and tabled 0L/1L languages. In this paper we compare AATPNS with some simple and expressive picture grammar models like(More)
