This paper presents a constraint logic programming model for the traveling salesman problem with time windows which yields an exact branch-and-bound optimization algorithm without any restrictive ...

In this paper we develop a discretized version of the dynamic programming algorithm and study its convergence and stability properties. We show that the computed value function converges quadratically ...

The Education Ministry has issued a letter saying that the school students of Russia and other countries aged 14 to 18, regardless of experience and knowledge in programming, are invited to take part ...
