## Some Segmentation Ideas

Continuing with my earlier post on Robocode, I’d like to describe some thoughts on  segmentation strategies.

So the basic idea is, we want to minimize our bins at all times. In effect, this means calculating the Maximum Escape Angle, calculating the arc formed by the intersection of the target and the circle of radius distance to target with center on our tank (that is, the orbital path our opponent could take), and then taking the ceiling of one half of the ratio (one half because a single shot will hit our opponent just as well as if hits the leftmost part of our opponent as the rightmost side).

Interestingly, we can adjust the Maximum Escape by adjusting the speed of our bullet. Given that, we can actually reduce or expand the number of bins as we desire- a useful ability when trying to maximize probability (since things are discrete, a change from N to N-1 bins can be fairly significant assuming the probability to hit is a uniform distribution at both ranges).

Furthermore, we can supplement our segmentation data by adjusting the range at which we fight, spiraling toward and away our opponent as necessary, in order to keep our targets at optimal distances.
