Research Type Theoretical We discuss the compatibility between envy-freeness up to any item (EFX) and various efficiency concepts. Additionally, we present polynomial-time algorithms for various settings. Our main contributions are summarized as follows. EFX + Max NSW + PO. We first consider binary valuation functions, where agents valuations for jobs are restricted to 1 or 0. We explore the characteristics of Max NSW schedules, focusing on fairness guarantees (approximate EFX) and efficiency guarantees (PO). Main Result 1: For any instance of FISP with binary valuations, there exists a Max NSW schedule that is 1/2-EFX and PO. Additionally, there exist instances where no Max NSW schedule can guarantee (1/2 + ε)-EFX for any ε > 0.
