• David's concept
• aka Supermarket Seen From Above

The point of this "game" is to illustrate the equalization of benefits=costs, by using a search cost scenario. It is not clear that even in the original this point was well illustrated.

The concept needs to be thought-out more clearly. Possibly this could be rethought in terms of the manager: whether to open new lines (and hire cashiers) or lose customers from the high waiting times, though this probably changes the original point of the game.

Problems in our implementation:

• initial version supporting two strategies
• search costs are not yet implemented --- there are currently two behaviors: choose the line with the least expected time (knowing only the number of carts and the number of goods in the last cart) or choosing randomly --- this is kinda of educational because it shows that for a certain ratio strategy does not matter, but it does transparently transmit the point
• customers are not implemented as agents so their behavior is not as flexible as it could be
