Hyper-converged cloud refers to an architecture that an operator runs compute and storage services on the same set of physical servers. Although the hyperconverged design comes with a number of benefits, it makes crucial operational tasks, such as capacity planning and cost analysis, fairly complicated. The problem becomes more onerous if we consider a complex distributed system, such as Ceph, ...

Hyper-heuristics are (meta-)heuristics that operate at a high level to choose or generate a set of low-level (meta-)heuristics to solve difficult search and optimisation problems. Evolutionary algorithms are well-known natureinspired meta-heuristics that simulate Darwinian evolution. In this article, we introduce an evolutionary-based hyper-heuristic in which a set of low-level heuristics compe...

Circular antenna array design is one of the most important electromagnetic optimization problems of current interest. The antenna must generate a pencil beam pattern in the vertical plane along with minimized side lobe level. In this paper we present non conventional method based on improved parameter of hyper beam exponent x. The circular array when implemented using hyper beam technique, ther...

This paper is concerned with the hybridization of two graph coloring heuristics (Saturation Degree and Largest Degree), and their application within a hyperheuristic for exam timetabling problems. Hyper-heuristics can be seen as algorithms which intelligently select appropriate algorithms/heuristics for solving a problem. We developed a Tabu Search based hyper-heuristic to search for heuristic ...
