Low Autocorrelation Binary Sequences
Not on the map. Why?
Abstract (arXiv)
Binary sequences with minimal autocorrelations have applications in communication engineering, mathematics and computer science. In statistical physics they appear as groundstates of the Bernasconi model. Finding these sequences is a notoriously hard problem, that so far can be solved only by exhaustive search. We review recent algorithms and present a new algorithm that finds optimal sequences of length N in time Theta(N,1.73N). We computed all optimal sequences for N≤ 66 and all optimal skewsymmetric sequences for N≤ 119.
