Fast equality saturation and equality graphs based on "egg: Fast and Extensible Equality Saturation" and "Relational E-matching".

This package provides e-graphs (see Data.Equality.Graph), a data structure which efficiently represents a congruence relation over many expressions

Secondly, it provides functions for doing equality saturation (see Data.Equality.Saturation), an optimization/term-rewriting technique that applies rewrite rules non-destructively to an expression represented in an e-graph until saturation, and then extracts the best representation.

Equality matching (see Data.Equality.Matching) is done as described in "Relational E-Matching"

For a walkthrough of writing a simple symbolic simplification program see the hegg symbolic tutorial.
