demes

Tools for describing and manipulating demographic models.

A demographic model describes one or more demes (or populations), how they change over time, and their relationships to one another. demes provides a self-contained and unambiguous in-memory description of a demographic model.

Please see the documentation for more details.

Goals

• A simple declarative high-level format for specifying demographic models. This format is intended to be human-readable and to make it easy to correctly specify models.
• A corresponding low-level format that is an entirely unambiguous and portable description of a model, which can be used by many different simulation frameworks as input. Thus, we can see part of the role of this package as compiling the high-level description of a model into the corresponding low-level description.
• Robust validation of models and reporting of errors for invalid models.
