Putting the magic in the machine since 1980.

One can visualize a combinatorial auction (with OR bids only) as a graph with two types of nodes: bids and items. Each bid node is labelled with the price of the bid and connected to all the items it is over. This is the visualization I have implemented in my combinatorial auction NetLogo model. It implements the branch-and-bounds algorithm on the branch-on-bids tree as found in my textbook.
