The optimization of land-use structure is the core of optimizing the allocation of land resources, including the optimization of quantity and space. However, traditional methods such as multi-objective programming model, gray system, landscape ecology are very difficult to make the space structure and the quantity structure unified effectively. To avoid the deficiencies mentioned above, this pa...

Planar dielectric EBG structures are formed by two-dimensional periodic dielectric inclusions in the dielectric slab. The main design parameters forming the frequencies of stopband are the shape of inclusions and their size, kind of slab it is formed in, lattice constant and both slab and inclusions permittivity constant. While there does not exist a general way how to determine the stopband ex...

Many portfolio optimization problems deal with allocation of assets which carry a relatively high market price. Therefore, it is necessary to determine the integer value of assets when we deal with portfolio optimization. In addition, one of the main concerns with most portfolio optimization is associated with the type of constraints considered in different models. In many cases, the resulted p...

Optimizing the hyperparameters and architecture of a neural network is long yet necessary phase in most applications. This consuming process can benefit from strategies designed to discard low-quality configurations quickly focus on more promising candidates. work aims at enhancing HyperNOMAD, library that adapts direct search derivative-free optimization algorithm tune both training simultaneo...
