In this paper, we investigate variable neighbourhood search (VNS) approaches for the university examination timetabling problem. In addition to a basic VNS method, we introduce variants of the technique with different initialisation methods including a biased VNS and its hybridisation with a...

In the present work, the dechanneling of protons in Si [110] is studied combining theoretical Monte-Carlo and phenomenological simulation results in the energy range E <Subscript> p </Subscript>=1.8-2.4 MeV.

In this paper, we present a random iterative graph based hyper-heuristic to produce a collection of heuristic sequences to construct solutions of different quality. These heuristic sequences can be seen as dynamic hybridisations of different graph colouring heuristics that construct solutions...
