Omac: A discrete wavelet transformation based negotiation agent

Abstract

This work describes an automated negotiation agent called OMAC which was awarded the joint third place in the 2012 Automated Negotiating Agent Competition (ANAC 2012). OMAC, standing for “Opponent Modeling and Adaptive Concession,” combines efficient OMAC making. Opponent modeling is achieved through standard wavelet decomposition and cubic smoothing spline; concessionmaking is made through setting the best possible concession rate on the basis of the expected utilities of forthcoming counter-offers.
