In addition, the authors present an algorithm utilizing the formalism of Petri nets to compute the degree of truth of the resulting answers to the queries. The degree of truth is computed in algebraic form based on the state equation which can be implemented in matrix computation in Petri nets.[SDGs]SDG16conference paper10.1109/CMPSAC.1997.625031https://doi.org/10.1109/CMPSAC.1997.625031
