Rugby

The problem of the best position for "kicking a conversion" in rugby is solved with a probabilistic method instead of an analytic one.

For detailed instructions on using the program, take a look at the info window from the Rugby model.

Click on one of the pictures to see a quicktime movie of the model:
The left boundary of the goal is 0, the right boundary of the goal is 20, and the kick line is at -20. There are 2000 kicks occuring simultaneously.
The left boundary of the goal is 20, the right boundary of the goal is 40, and the kick line is at -20. There are 2000 kicks occuring simultaneously.
The left boundary of the goal is 0, the right boundary of the goal is 35, and the kick line is at -30. There are 1000 kicks occuring simultaneously.

When comparing these first two examples, please note that when the goal is moved to the right the center of the distribution moves down.
