We propose a hybrid discrete grey wolf optimizer (HDGWO) in this paper to solve the weapon target assignment (WTA) problem, a kind of nonlinear integer programming problems.To make the original grey wolf optimizer (GWO), which was only developed for problems with a continuous solution space, available in the context, we first modify it by adopting
Tangible technologies provide interactive links between the physical and digital worlds, thereby merging electrosex-insertables the benefits of physical and virtual manipulatives.To explore the potentials of tangible technologies for learning linear equations, a tangible manipulative (TM) was designed and developed.A prototype of the initial TM was
The process of preparation and realization of manipulation of consciousness of man or mass consciousness plays an enormous role in realization of influence on the emotional state, motivation, rational thinking with the purpose of change of models of behavior of certain target audiences, that strengthens negative psychological influence in turn.Subo
Seasonal migrations allow access to temporally varying resources and individuals may show fidelity to specific locations, particularly for important life processes such as reproduction.Polar bears (Ursus maritimus) are a sea ice-dependent species that migrate between marine and terrestrial habitats, the latter being important for parturition and ea
