Essentially, each winning bid's value is scored "below the line" (e.g., 3 Spades nets 90 points below the line) and overtricks, bonuses, etc. are scored
Generalized first-price auction the GFP mechanism can be ascribed to its bidding interface, and that adopting a more expressive bidding interface guarantees the existence of an efficient Nash equilibrium under complete information as well as an efficient Bayes-Nash equilibrium under incomplete information. Generalized first-price auction The generalized first-price auction (GFP) is a non-truthful auction mechanism for sponsored search (a.k.a. position auctions). In sponsored search "n" bidders compete for the assignment of "k" slots. Each slot has an associate click-through rate, the click-through rates are decreasing from top to bottom. The GFP mechanism asks each bidder for a bid. Then the highest bidder gets
