This repository provides a solution to the standard Capacitated Vehicle Routing Problem with Time Windows (CVRPTW). In a CVRPTW, we aim to optimize the routes of a fleet of vehicles serving customers ...

A group of math teachers in Tucson, Arizona, came under fire for their Halloween costumes this weekend. The teachers’ bloodied white t-shirts with the phrase “Problem solved” written across the chest ...

Abstract: To accurately simulate the thin layer of linear dispersive media, an improved 3-D finite-difference time-domain (FDTD) method is proposed. The inclusion of a weak conditionally stabilized ...

In 1945, as the first atomic bomb exploded in the New Mexico desert, Enrico Fermi stood miles away, holding a few scraps of paper. As the shockwave rolled toward him, he dropped the papers and watched ...

Abstract: In this article, a model-free Q-learning algorithm is proposed to solve the tracking problem of linear discrete-time systems with completely unknown system dynamics. To eliminate tracking ...
