My first thought was an adjacency list with something to indicate forbidden edges (for a dot inside a cycle), so it might help. The problem isn't that simple though, as more and more moves are made whose in what cycle and can make waht move is a good deal less than clear.

FWIW if have written some AS2 classes some time ago that implement a graph by using adjacenty lists.

The game starts with a few randomly distributed dots. There is one move and 2 restrictions. Move: draw a line for a dot to itself (a loop) or to another dot. Any line drawn has a new dot on it. Restriction 1: no more than 3 lines from any dot. Restriction 2: no lines can cross. Simple game, but the data structure to keep track of the game and in particular to handle restriction 2 is a bear. How do you tell when a dot has been encircled by a line? The game is, of course based on graph theory, and you can represent a graph in several ways, but how to determine that it remains planar? I haen't begun to think about the visual part of this, if I don't have a reasonable data structure I can't teach a computer to play the game. Any ideas? Hints? Wildly improbable ideas? -- Weldon MacDonald _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
