This paper demonstrates the capability of four dipoles antenna (two-dimensional array) to steer the beam to arbitrary direction. A combination of genetic algorithm and array analysis based on the Induced EMF method optimised the input excitation of each dipole to maximise the main lobe to any azimuth direction. The optimisation is performed using MATLAB software. The Induced EMF method incorporates...
Notice of Violation of IEEE Publication Principles"Design of Digital FIR Filters Using Differential Evolution Algorithm Based on Reserved Gene"by Qingshan Zhao and Guoyan Mengin the Proceedings of the 2010 International Conference of Information Science and Management Engineering, August 2010, pp. 177-180After careful and considered review of the content and authorship of this paper by a...
Biogeography based optimization (BBO) is a new inclusive vigor based on the science of biogeography. Biogeography is the schoolwork of geographical allotment of biological organisms. BBO employs migration operator to share information between the problem solutions. The problem solutions are identified as habitat and sharing of features is called migration. In this communication, BBO algorithm is matured...
A modified dynamic differential evolution was proposed for discrete optimization. Based on the new framework of dynamic differential evolution, two additional operators were used to extend the dynamic differential evolution to the field of discrete optimization. The first operator was the mapping operator, which could map the continuous value into zero or one. The other new operator was the boundary...
In this paper, the multiple trajectory search (MTS) is presented for large scale global optimization. The MTS uses multiple agents to search the solution space concurrently. Each agent does an iterated local search using one of three candidate local search methods. By choosing a local search method that best fits the landscape of a solutionpsilas neighborhood, an agent may find its way to a local...
Uniform amplitude arrays on a periodic lattice usually have to be thinned if a low sidelobe level is required. The choice of a thinning configuration has to be performed using an optimization algorithm. If the number of deactivated elements is not kept under control, good array configurations in terms of sidelobe level could result in large losses of directivity. In order to satisfy a constraint on...
