We consider computationally expensive blackbox optimization problems and present a method that employs surrogate models and concurrent computing at the searc...

We study a new variant of the well-studied Vehicle Routing Problem with Time Windows (VRPTW), called the fragility-constrained VRPTW, which assumes that ...
