Pars agent: Hybrid time-dependent, random and frequency-based bidding and acceptance strategies in multilateral negotiations

Abstract

We propose our Pars agent, one of the ANAC 2015 winners in multilateral negotiation tournaments. In this challenge, any agreement is made through acceptances issued by all parties involved in a trilateral negotiation. Pars agent uses a hybrid bidding strategy that combines behaviors of time-dependent, random and frequency-based strategies to propose a high utility offer close to the opponents bids and to increase the possibility of early agreement. © Springer International Publishing AG 2017.
