TAC Travel

In the TAC shopping game, each “agent” (an entrant to the competition) is a travel agent, with the goal of assembling travel packages (from TACtown to Tampa, during a notional 5-day period). Each agent is acting on behalf of eight clients, who express their preferences for various aspects of the trip. The objective of the travel agent is to maximize the total satisfaction of its clients (the sum of the client utilities).

Lemonade Stand Game

It is summer on Lemonade Island, and you need to make some cash. You set up a lemonade stand on the beach (which goes all around the island), as do two other entreupeneurs. There are twelve places to set up, evenly spaced around the island. Your price is fixed, and all customers go to the nearest lemonade stand. Every night, everyone moves under cover of darkness (simultaneously) and in the morning, their locations are fixed. There is no cost to move. After 100 days of summer, the game is over. The utility of the repeated game is the sum of the utilities of single-shot games.

TAC Ad Auctions

The TAC Ad Auctions (TAC/AA) game presents a realistic sponsored search environment for a simulated advertising scenario. Advertisers represent retailers in a simplified home entertainment market, bidding to place ads before users searching on product keywords.

Game entrants design and implement bidding strategies for the advertisers, while behaviors of the search engine and users are simulated by the server.
The TAC/AA tournament pits advertiser agent strategies against each other, evaluating each in terms of sales profit net of advertising costs.

TAC Market Design

TAC Market Design (reverse TAC or CAT) software agents represent market makers whose goals are to attract potential buyers and sellers as customers, and then to match buyers with sellers. The market makers compete with one another in doing this, such as the London Stock Exchange competes with the NYSE for the business of stock traders.

TAC Supply Chain Management

The latter involves planning and coordinating activities of organizations across the supply chain, from raw material procurement to finished goods delivery. In this game, agents compete to secure customer orders and components required for production of these orders. The game captures many of the compGame Master: Tim Millerlexities of actual supply chains, where both demand and supply fluctuate and each manufacturer has limited production capacity.
