For every college basketball fan, there come points in your life when you have to make some decisions, tough decisions. Who will be in your Final Four this year? Will the number-one seeds ride the bracket to the Final Four? Who’s the 5–12 seed upset? How will the Big Ten fare?

We’re heading for the tipoff of what I feel is the greatest sports weekend in the United States. While gearing up for a lot of game watching, I found a great blog post from last March by Jeff Todd, one of our Commercial Sales Account Managers, called “March Madness in Mathematica.” In it he explained how he created an interactive NCAA Men’s Basketball bracket in Mathematica.

Here’s an updated Mathematica notebook for the 2010 NCAA Men’s Basketball Tournament. The bracket can be opened and edited with Mathematica and Mathematica Home Edition. I’m sure you’ll find this application as useful as I have.

I wish you the best of luck in your picks this year. Have fun, and let the games begin!
