To be just, we mention that Yanov schemes of programs were among the first graphical models and major results in the area of place-transition nets that have obtained 70th in the USA by Hack, Molloy and Murata. Then Gerault, Valette, Marsan and Chiola essentially developed them in France and Italy. Then Jensen in Denmark introduced and developed the concept of colored nets.
Besides, vector addition systems of Karp and Miller represent the same concept from a mathematical point of view, recently developed in multiset rewriting systems by Cervesato.
How do you feel about this new technology being coined with your name?
As a modest person, I would rather say that the decision to bring in my name has been adopted without my influence. From the other side, why should we be unjust to so many people by forgetting their names?
Without disparaging the contribution of Carl Petri on the initial stage, we state that modern place-transition nets are essentially different, refined and developed by many brilliant people.
As for the central part of the model that influences the entire theory, we undoubtedly should mention people who introduced new concepts: the maximal firing strategy of Salwicky described in works of Burhard, cause and effect nets of Czaja, algebraic nets of Kotov, colored nets of Jensen, etc.
Otherwise let us call them all “place-transition” nets.
What argument typically goes against your opinions on the controversial topics you mentioned?
As for graphical languages of programming, they start from Yanov schemes of programs, continue in R-technology of programming of Velbitsky and finally resolve in UML of Booch, which part is represented now by place-transition nets.
Many people say that major application field of place-transition nets are restricted by modeling tasks only. They say that all of the projects that brought nets to the enterprise level of implementation were unsuccessful.
They are right concerning Petri nets. However, our nets with the multiple firing strategy run fast and open new prospects for their wide practical application. Moreover, a Petri net is a special case of our nets. Only a huge, real-life project could resolve the issue, and we invite big companies to cooperate.
What kind of impact would this technology have?
Currently, typical processors have reached their limitations of speed. Quantum computers are very far in the future, and Sleptsov computers, implemented as a matrix of computing memory, will run very fast and massively parallel. It will be cheap, and it opens wide prospects of applications, included applications that are embedded in everyday devices to new kinds of supercomputers. We only use software models of it now, but hope to see it implemented directly into hardware one day. This innovation has the potential to generate major change in the realm of technology.
