    ... a network graph of the top fighters in PRIDE. Nodes are fighters scaled according to (wins - losses), edges point from winner to loser with a label indicating how the fight ended. Fights in which the loser had never won a match or the winner hadn't won at least 3 more than he'd lost were culled.
    Very nice.
    Are you at all familiar with Neo Martinez's work using network theory and similar graphical approaches as what you presented here to characterize food webs?

    Hey, I've got a Google Spreadsheet with all the UFC fights in it that I'd like to patch up with your observations about which submissions were used when. Any way I can get that from you?

    Not until now. His ecological graphs are similar to some work I did last year on a graph theoretical analysis of systemic risk in the financial system.

    The network diagram I posted before is the by-product of my looking into whether a graph-based approach could be used to auto-rate fighters based not only on how many fights they've won, but against whom.

    Never realize how many times the rear naked choke has been used, i thought the guillotine would be the most used for sure.

    I wasn't planning on doing the x beat y who beat z, so x must be able to beat z kind of thing. More like walking the graph of victories out from a given fighter, tallying up wins without double-dipping at any node.

    hey Jack, why does that first graph you posted taper off at the end? are there less submissions taking place recently, or did you include data from this current unfinished year and give that year it's own place?

    I don't know the proper word for "place."

    The unfinished year:

    Can you make this data available for others who would like to play with it. Like me ;)

    Of course. I plan to make the spreadsheets publicly available as soon as the data is clean.
