In a multi-unit combinatorial auction, reverse auction, or exchange, a number of bids can be received, with each bid including one or more items and for each item a desired quantity thereof. Each bid also includes a price. A number of unique combinations of bids can be formed from the received bids, and the one combination of bids which represents the best value in terms of an auction setting, a reverse auction setting and/or an exchange setting can be determined. Thereafter, the bids forming this combination can be declared the winning bids of the auction, reverse auction or exchange.

Combinatorial auction branch on bid searching method and apparatus

A method of processing an exchange includes providing a solver/analyzer for determining a solution that includes at least one of a winning allocation and feasible allocations. At least one bid is received at the solver/analyzer, with each bid including at least one item and an associated price. Exchange description data (EDD) is associated with the at least one bid. The EDD is also received at the solver/analyzer. The processing of the at least one bid is modified in accordance with the at least one feature included in the EDD.
