Combinatorial auctions allow buyers to express preferences over bun- dles of items. The Primal-Dual (PD) auction developed by de Vries et al. (2007) is an efficient ascending combinatorial auction which, given certain conditions on buyers valuations, achieves Vickrey-Clarke-Groves (VCG) payments. The Universal Competitive Equilibrium (UCE) auction by Mishra and Parkes (2007) is a generalization of
