"Some Hamilton Paths and a Minimal Change Algorithm",
Journal of the ACM, Vol.31, pp.19--29 (1984).
This article proves the theorem that
the neighbor-swap graph on n-bit strings (combinations)
admits a Hamilton path if and only if
it is trivial or the number of 0s and 1s are both odd.
"Hamilton Paths in Graphs of Linear Extensions for Unions of Posets",
SIAM Journal on Discrete Mathematics, Vol.5, Nr.2, pp.199-206 (1992).
This article (constructively) proves the sufficiency part of
the conjecture that
the neighbor-swap graph on the permutations of a multiset
admits a Hamilton path
if and only if
it is trivial or there are at least two elements in the multiset
that occur an odd number of times.
F. Ruskey, A. Williams.
"The Coolest Way to Generate Combinations",
Vol.309, pp.5305-5320 (2009).
This article presents a simple algorithm to generate all
combinations (n-bit strings) by prefix rotations.
