Given a set of flight legs to be flown by a single type of aircraft, the simultaneous aircraft routing and crew scheduling problem consists of determining a...

Let <i>G</i> be a multigraph containing no minor isomorphic to <i>K</i>_3,3 or <i>K</i>₅<i>e</i> (where <i>K</i>₅<i>e</i> de...

The standard way to solve the static economic dispatch problem with transmission losses is the penalty factor method. The problem is solved iteratively by a...

In several arc routing problems, it is necessary to take turn penalties into account when designing a solution. Traditionally, this is done through a trans...

Systematic change of neighborhood within a possibly randomized local search algorithm yields a simple and effective metaheuristic for combinatorial and glo...

This paper examines dynamic advertising and promotion strategies in a marketing channel where the retailer promotes the manufacturer's product, and the manu...

Weber's problem is to locate a facility in the Euclidean plane in order to minimize total transportation costs from that facility to a given set of users wi...
