Lattice point methods for combinatorial games
(Advances in Applied Mathematics, 2011-01-01)
We encode arbitrary finite impartial combinatorial games in terms of lattice points in rational convex polyhedra. Encodings provided by these lattice games can be made particularly efficient for octal games, which we generalize ...
A Comparison of Values around Cruise Tax in Iceland and Alaska
Cruise ships pose many environmental harms: they emit more black carbon and CO₂ per passenger-mile than any other vehicle, discharge untreated sewage and wastewater into the open ocean, carry large quantities of heavy fuel ...
