We develop the notion of E-graphs modulo theories to handle well-known cases of combinatorial explosion when running equality saturation for theories including associative and commutative (AC) operators. We connect this to the well-studied word problem, which can be solved for AC with Buchberger’s algorithm; this gives a foundation for integrating fast theory-specific methods into E-graphs.
