摘要
The Winner Determination Problem (WDP) in Combinatorial Auctions comes up in a wide range of applications. Linear Programming (LP) relaxations are a standard method for approximating combinatorial optimisation problems. In this paper we propose how to encode the WDP so that it can be approximated with AD(3). Moreover, we contribute with PAR-AD(3), the first parallel implementation of AD(3). We show that while AD(3) is up to 4.6 times faster than CPLEX in a single-thread execution, PAR-AD(3) is up to 23 times faster than parallel CPLEX in an 8-core architecture.
