To review the established mathematical proofs and core invariants for two famous International Mathematical Olympiad challenges: the 2011 windmill problem and the 1988 Problem 6.
Analyzed the discrete geometry of the 2011 IMO windmill process rotating across n points in general position.
Examined the algebraic descent method of Vieta jumping applied to the Diophantine equation (a² + b²) / (ab + 1) = k.
Demonstrated that the rotating windmill line maintains a discrete invariant separating point sets into equal halves, ensuring every point acts as a pivot infinitely often.
Confirmed that root descent via the quadratic x² - kb·x + (b² - k) = 0 restricts the integer ratio k strictly to perfect squares.
