Some algorithms arising in the proof of the Kepler conjecture
Abstract
Description
By any account, the 1998 proof of the Kepler conjecture is complex. The thesis underlying this article is that the proof is complex because it is highly under-automated. Throughout that proof, manual procedures are used where automated ones would have been better suited. This article gives a series of nonlinear optimization algorithms and shows how a systematic application of these algorithms would bring substantial simplifications to the original proof. This article includes a discussion of quantifier elimination, linear assembly problems, automated inequality proving, and plane graph generation in the context of discrete geometry.
