To identify and characterize the mathematical structures—specifically invariants, combinatorial geometry, and dynamical systems—that define the difficulty of elite competition problems.
Analyzed structural mechanisms of extreme Olympiad problems, centering on the 2011 International Mathematical Olympiad windmill problem (Question 2).
Modeled continuous line rotation and pivot switching as a discrete dynamical system on a complete graph Kn with symmetry group Sn over a one-dimensional torus (R/πZ).
Showed that problem difficulty clusters around invariant theory, combinatorial geometry, and logical self-reference rather than computational complexity.
Demonstrated that the windmill pivot mechanism resolves into a permutation cycle driven by orientation modulo π, parity invariants, and configuration-space rotational symmetry.
