Time-Space Tradeoffs in SAT: No Universal Golden-Ratio Constants — E8 Intelligence Research
FINDING: Time-space tradeoffs for SAT and related problems yield explicit lower-bound constants tied to algorithmic resource geometry, but no universal golden-ratio constants emerge from these sources. | MATH: The core tradeoff is typically expressed as \(T \cdot S = \Omega(n^{2})\) or stronger forms like \(T \cdot S^{1-\epsilon} = \Omega(n^{2-\epsilon})\) for SAT; the opaque-set result gives explicit lower bounds (e.g., length \(> 2\pi + \delta\) for unit disc, with \(\delta\) a computable constant) via Kawamura–Moriyama–Otachi–Pach method and Steinerberger's observation. | CONNECTION: The opaque-set lower bound involves Euclidean geometry (unit circle/square) — the optimal opaque set for a disc is conjectured to be a Steiner tree with angles \(120^\circ\), which relates to hexagonal/crystallographic symmetry (root system \(A_2\), honeycomb lattice). The time-space tradeoff for hashing tables (Kuszmaul) involves load factors near \(1/e \approx 0.3679\) and \(0.6321\) (complement), whi Author: Andrew Stewart Caldin, Independent Researcher, UK.
