Abstract

This study investigates the impact of the number of fixed constraints on automated negotiation outcomes in a multi-issue negotiation scenario. Specifically, we analyze how the variation in the fixed constraints set by each negotiating agent influences social welfare, agreement frequency, and negotiation time. The negotiation protocol considers fixed constraints and evaluates their effects on the efficiency and feasibility of reaching agreements. Simulation results reveal that as the number of fixed constraints increases, social welfare and agreement frequency tend to decrease while negotiation time remains relatively unchanged. These findings highlight the importance of understanding the role of fixed constraints in optimizing negotiation outcomes and provide insights for designing more effective automated negotiation protocols.
