pyssa 0.5.4

Python package for stochastic simulations

Stochastic Simulation Algorithms in Python

Introduction

pyssa is a Python package for stochastic simulations. It offers a simple api to define models, perform stochastic simulations on them and visualize the results in a convenient manner.

Install

Install with pip:

$ pip install pyssa

Documentation

• General: https://pyssa.readthedocs.io.

Usage

from pyssa.simulation import Simulation

sim = Simulation(V_r, V_p, X0, k)
sim.simulate(max_t=150, max_iter=1000, chem_flag=True, n_rep=10)

Plotting

sim.plot()

Accessing the results

results = sim.results

Benchmarks

We chose numba after extensive testing and benchmarking against python and cython implementations.
