+/**
+ * This kind of AI is parameterized by a percentage p.
+ * The computation consists in finding all the N possible rounds for the
+ * current rack/board, and sorting the list.
+ * 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).
