E-ALS: Approximation-Potential-Aware E-Graph Rewriting for Approximate Logic Synthesis
E-ALS is proposed, an e-graph-based framework for approximation-aware structural search that combines Function-Reduced Saturation, an ALS-coupled surrogate, search-based extraction, and budget-guided refinement to identify approximation-friendly equivalent structures.
