Mathematician Richard Evan Schwartz of Brown University tackled the problem in a recent study by working backward from an existing polyhedral torus to answer questions about what would be needed to ...

Abstract: This paper investigates the optimal guidance for hypersonic vehicles to achieve the maximum downrange. To handle the complex constraints during the reentry flight, we design a novel barrier ...

Artificial intelligence has attained an impressive series of feats—solving problems from the International Math Olympiad, ...
