synopsis:           Fast equality saturation in Haskell

description:        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.
                    .
                    For a monadic interface to e-graphs check out
                    "Data.Equality.Graph.Monad" (home to the convenient
                    function 'represent').
                    .
                    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](https://github.com/alt-romes/hegg#equality-saturation-in-haskell).
                    .
