EXAMPLE OF A MARKET ALGORITHM

3 BUYERS and 4 SUPPLIERS Buyer X : (50 A, 10 B) Buyer Y : (20 B, 30 C) Buyer Z : (40 A, 20 C, 10 D)

BUNDLING Bundle 1: (90 A) Negotiated contract Bundle 2: (30 B, 50 C) Sealed bid auction Bundle 3: (10 D) Dynamic auction

Y Narahari, Computer Science and Automation, Indian Institute of Science

EXAMPLE OF A MARKET ALGORITHM

Sealed Bid Combinatorial Auction Supplier P : (10 B, 10 C, p) Supplier Q : (30 B, q) Supplier R : (50 C, r) Supplier S : (20 B, 50 C, s)

An optimization algorithm decides the best bids and handpicks the optimal subset of bids, based on cost, delivery times, etc.
