Abstract

FINDING: The "hardest" competition problems (IMO/ Putnam) are not defined by computational complexity but by a single, non-obvious structural insight — e.g., the 2011 IMO windmill problem reduces to a parity/invariant argument on point configurations, and the Boolos logic puzzle reduces to a ternary truth-functional fixed point. | MATH: Windmill problem: For n points in general position, a rotating line ("windmill") that always reflects about the pivot point visits every point infinitely often iff n ≡ 0 or 1 (mod 3) — the invariant is the number of points on each side of the line mod 3. Boolos puzzle: 3 gods (True, False, Random) — solution uses a self-referential question of form Q(A) = "If I asked you P, would you say 'ja'?" — reduces to a Boolean algebra over {ja, da} with a fixed-point operator. | CONNECTION: The mod-3 invariant in the windmill problem is a discrete analogue of the golden ratio's self-similarity — both encode a 3-fold rotational symmetry (crystallographic point gro Author: Andrew Stewart Caldin, Independent Researcher, UK.
