However, online auction sites, unlike live auctions, usually have an automatic bidding system which allows a bidder to enter their maximum acceptable bid. This is a hidden or proxy bid, known to the system, but not any other bidders; during the auction the actual bid is incremented only enough to beat the existing highest bid. For example, if ...

The auctioneer uses the final bids to compute the ...
The flip graphs of a quadrilateral (top-left), a pentagon (top-right), and a hexagon (bottom). Examples of flips in dimension 1 (top-right), 2 (top-left and central row), and 3 (bottom row). In mathematics, a flip graph is a graph whose vertices are combinatorial or geometric objects, and whose edges link two of these objects when they can be ...
A uniform price auction otherwise known as a "clearing price auction", pay-as-clear [1] or marginal price auction, "marginal price system" (MPS), [2] is a multiunit auction in which a fixed number of identical units of a homogenous commodity are sold for the same price. Each bidder in the auction may submit (possibly multiple) bids, designating ...
