Introduction

Simulation parameters are stored in instances of fwdpy11.ModelParams. Once initialized, instances of this class are immutable, or “frozen”.

This class can only be initialized via explicit use of kwargs. In many of the vignettes, you will see that a dict is filled first, and then used to construct a ModelParams object with the ** syntax. The reason to use a dict is because of the immutability of the ModelParams instances. Sometimes, it is convenient to add to existing lists of things in the dict. Such modifications are not allowed on an initialized ModelParams.

Many of the vignettes that follow have a note section at the top. These notes tell you what kwarg for the ModelParams initializer is being discussed.
