Automated bidding strategies for an auction of a single good with a known valuation are fairly straightforward; designing strategies for simultaneous auctions with interdependent valuations is a more complex undertaking.

The benchmark challenge for competing agents - to buy and sell multiple goods with interdependent valuations in simultaneous auctions of different types - encourages competitors to apply innovative techniques to a common task.
