*DE-Sim*: a Python-based object-oriented discrete-event simulator for modeling complex systems
==============================================================================================

*DE-Sim* is an open-source, Python-based object-oriented discrete-event
simulation (DES) tool that makes it easy to use large, heterogeneous
datasets and high-level data science tools such as
`NumPy <https://numpy.org/>`__,
`Scipy <https://scipy.org/scipylib/index.html>`__,
`pandas <https://pandas.pydata.org/>`__, and
`SQLAlchemy <https://www.sqlalchemy.org/>`__ to build and simulate
complex computational models. Similar to
`Simula <http://www.simula67.info/>`__, *DE-Sim* models are implemented
by defining logical process objects which read the values of a set of
variables and schedule events to modify their values at discrete
instants in time.

To help users build and simulate complex, data-driven models, *DE-Sim*
provides the following features:

-  **High-level, object-oriented modeling:** *DE-Sim* makes it easy for
   users to use object-oriented Python programming to build models. This
   makes it easy to use large, heterogeneous datasets and high-level
   data science packages such as NumPy, pandas, SciPy, and SQLAlchemy to
   build complex models.
-  **Stop conditions:** DE-Sim makes it easy to terminate simulations
   when specific criteria are reached. Researchers can specify stop
   conditions as functions that return true when a simulation should
   conclude.
-  **Results checkpointing:** DE-Sim makes it easy to record the results
   of simulations by using a configurable checkpointing module.
-  **Reproducible simulations:** To help researchers debug simulations,
   repeated executions of the same simulation with the same
   configuration and same random number generator seed produce the same
   results.
-  **Space-time visualizations:** DE-Sim generates space-time
   visualizations of simulation trajectories. These diagrams can help
   researchers understand and debug simulations.

Projects that use *DE-Sim*
--------------------------

*DE-Sim* has been used to develop
`WC-Sim <https://github.com/KarrLab/wc_sim>`__, a multi-algorithmic
simulator for `whole-cell models <https://www.wholecell.org>`__.

Examples
--------

-  `Minimal simulation <de_sim/examples/minimal_simulation.py>`__: a
   minimal example of a simulation
-  `Random walk <de_sim/examples/random_walk.py>`__: a random
   one-dimensional walk which increments or decrements a variable with
   equal probability at each event
-  `Parallel hold (PHOLD) <de_sim/examples/phold.py>`__: model developed
   by Richard Fujimoto for benchmarking parallel DES simulators
-  `Epidemic <https://github.com/KarrLab/de_sim/blob/master/de_sim/examples/sirs.py>`__:
   an SIR model of an epidemic of an infectious disease
