E-Graphs Support Custom Containers To Reduce Blowup

A technical post demonstrates how Egglog, an e-graph framework written in Rust with Python bindings, supports custom container types and higher-order functions to represent algebraic identities (associativity, commutativity, distributivity) and constant folding without modifying core e-graph internals. The article shows examples converting binary addition trees to multisets or sorted lists, explains congruence and rebuilding for containers, and highlights reduced e-graph size blow-up.
