Chess has a game tree complexity of 10^123, but how do you measure GTC for something like Jeopardy? For each question there is only one right answer, and therefore only one right move and the next question has no relation or dependence upon the question before it. So comparing jeopardy and chess seems like apples and oranges to me, no?</span></font></div>

And so based on that criteria, it is a step forward no matter how you slice it.</span></font></div>

<p class="MsoNormal"> </p><p class="MsoNormal">Jeopardy isn’t over however. It is only a matter of time before a competing team wants to play machine against machine, or even a three-way all machine matchup. Note that there are today about a couple dozen top chess computers cheerfully pummeling each other, with the results being broadcast for all the worlds people with far too much time on their hands to watch in pointless fascination. Those games are in some ways more interesting to watch than human-human or human-machine games, because they tend to be so technically clean and positional, so theoretical.</p>
