When debugging erroneous patterns, a common task is to identify which conditions or constraints of a query caused some model elements to appear in

Our approach is based on graph pattern matching concepts, specifically nested graph conditions with distance constraints, as well as graph algorithms for calculati

We believe that it is more useful to regard TGGs as just graph grammars with “batteries included”, meaning that TGG-based tools provide simple, default execution strategies, together with algorithms for incremental change propagation. Especially in ca

The challenge was to generate interesting puzzles with a reasonably small number of elements and reasonably complex series of steps required for the solution. Being educated in graph tra

Sesqui-Pushout Rewriting with Type Refinementsnal and the copy obtain the same context, i.e. all incoming and outgoing edges of the original are copied as well. This behaviour is not satisfactory in practical examples which require more control over the context cloning process. In this paper, we provide such a control mechanism by allowing each

Model Checking Reconfigurable Petri Nets with Maude of reconfigurable Petri nets. These are Petri nets with a set of rules for changing the net dynamically. We obtain model checking by converting reconfigurable Petri nets to specific Maude modules and using then the LTLR model checker of Maude. The main result of this paper is the correctness of thi
