Generating cyclic pivot Gray codes for well-ordered -degenerate graphs in constant amortized time
Lei Dong, Dennis Wong, Bowie Liu +4
A graph is -degenerate if there exists an ordering of its vertices such that each vertex has at most neighbors in with . A…

Generating pivot Gray codes for spanning trees of complete graphs in constant amortized time
Bowie Liu, Dennis Wong, Chan-Tong Lam +1
We present the first known pivot Gray code for spanning trees of complete graphs, listing all spanning trees such that consecutive trees differ by pivoting a single edge around a v…

Recursive and iterative approaches to generate rotation Gray codes for stamp foldings and semi-meanders
Bowie Liu, Dennis Wong, Chan-Tong Lam +1
We first present a simple recursive algorithm that generates cyclic rotation Gray codes for stamp foldings and semi-meanders, where consecutive strings differ by a stamp rotation.…
