2011 IMO Windmill Problem: Unexpected Difficulty and Parity-Based Solution — E8 Intelligence Research

FINDING: The 2011 IMO windmill problem (Q2) is cited as unexpectedly hard; no specific 2025/2026 IMO problems are yet released or detailed in the provided text. | MATH: No equations, constants, or ratios are extractable from the given text. The problem involves finite point sets in general position and a dynamic line (windmill) process; its solution uses parity arguments and extremal configuration analysis, but no numeric constants appear. | CONNECTION: No geometric harmony ratios (0.382, 0.618, 0.786, 1.618, 2.618), base-60, or crystallographic symmetries are present or implied. | DEPTH: 1 — The text contains only video titles and descriptions, not the mathematical content itself. No new mathematical insight, constant, or structural discovery is provided. The reference to the 2011 problem is historical, not a new finding.
