Abstract

We describe a tool that can compute a differential equation for the mean occurrence counts of a fixed graph observable in a given stochastic graph transformation system. It is an open problem whether the function that gives the mean occurrence count of the graph motif at a fixed time on the positive real line is approximable to arbitrary precision. However, the tool allows to express common practices to approximate the function using mean-field and refined approximation techniques. In the long term, we plan an extension to stochastic bisimulation checking for graph transformation systems
