Query: Implementing a Method for Stochastization of One-Step Processes in a
  Computer Algebra System   When modeling such phenomena as population dynamics, controllable ows, etc.,
a problem arises of adapting the existing models to a phenomenon under study.
For this purpose, we propose to derive new models from the rst principles by
stochastization of one-step processes. Research can be represented as an
iterative process that consists in obtaining a model and its further re nement.
The number of such iterations can be extremely large. This work is aimed at
software implementation (by means of computer algebra) of a method for
stochastization of one-step processes. As a basis of the software
implementation, we use the SymPy computer algebra system. Based on a developed
algorithm, we derive stochastic di erential equations and their interaction
schemes. The operation of the program is demonstrated on the Verhulst and
Lotka-Volterra models.
