|
|
* The chosen round is the n'th element of the sorted list, such that n/N

|
* is closest to the percentage p.

|
* A percentage of 0 should always return the best round (i.e. the one with
|
|
* the highest score), while a percentage of 1 should return the worst one.
|
|
* This kind of AI will never change letters (unless it cannot play anything,
|
|
* in which case it just passes without changing letters).
