Yesterday I wrote an algorithm in Java to generate de Bruijn sequences. But I had a breakthrough after reading:
K. Cattell, F. Ruskey, J. Sawada, M. Serra, C.R. Miers, Fast algorithms to generate necklaces, unlabeled necklaces, and irreducible polynomials over GF(2)
It has an algorithm which generates Lyndon words [...]
Not so long ago I encountered something called the de Bruijn sequence. For now I’ll only use this for an alphabet of (0,1), binary. But everything said here could also be applied to other alphabets. In this post I’ll describe what this sequence is, and how you can generate them, using Lyndon words.
