However, due to a variety of reasons, real-life systems often record only a subset of all events taking place. For

Automatic Decomposition of Petri Nets into Automata Networks – A Synthetic Accountulate this problem as the transformation of an ordinary, one-safe Petri net into a flat, unit-safe NUPN (Nested-Unit Petri Net) and define a quality criterion based on the number of bits required for the structural encoding of markings. We propose various transformation methods, all of which we impl

Data Centric Workflows for Crowdsourcingreturned results. A challenge to solve intricate problems is to define orchestrations of tasks, and allow higher-order answers where workers can suggest . rather than a .. Another challenge is to guarantee that an orchestration with correct input data terminates, and produces correct output data. Th

On the High Complexity of Petri Nets ,-Languagesy: the Borel and Wadge hierarchies of the class of .-languages of (non-deterministic) Petri nets are equal to the Borel and Wadge hierarchies of the class of .-languages of (non-deterministic) Turing machines. We also show that it is highly undecidable to determine the topological complexity of a Pe

A New Property of Choice-Free Petri Net Systemsorresponding reachability graphs and to use them in a pre-synthesis phase in order to quickly reject inadequate transition systems, and provide fruitful error messages. The same is true for simultaneous syntheses problems. This was exploited for the synthesis of choice-free nets for instance, for wh

On-the-Fly Synthesis for Strictly Alternating Gamesponents. We develop an algorithm for deciding the winner of the game and suggest a notion of alternating simulation in order to speed up the computation of the winning strategy. The theory is applied to Petri net games, where the strictly alternating games are in general undecidable. We consider sof
