“…The proposed algorithm is tested on six standard function and the obtained results are compared with those driven from IWO [13], CA, harmony search (HS) [9], PSO and GA. In addition, the numeric results for modified versions of IWO [11], CA [1] and HS [15] are also presented. The results are obtained by running over 10 times independent simulations on each optimization algorithm.…”

This paper introduces a novel optimization algorithm that is based on the basic idea underlying the bisection root-finding method in mathematics. The bisection method is modified for use as an optimizer by weighting each agent or vertex, and the algorithm developed from this process is called the weighted vertices optimizer (WVO). For exploitation and exploration, both swarm intelligence and evolution strategy are used to improve the accuracy and speed of WVO, which is then compared with six other popular optimization algorithms. Results confirm the superiority of WVO in most of the test functions.

“…IWO as a metaheuristic algorithm was effectively applied for control of SLL as well as desired nulls for a planar array [8]. Over the years few variations of IWO have been explored to a great degree of success in tackling null control problem of conventional antenna arrays [9], [10]. The ability of an antenna to radiate at multiple frequencies has led to its rampant utilization in the fields of 5G, satellite, RADAR and other wireless communications.…”

Design of antenna arrays involving fractal concepts have resulted in the evolution of new fractal antenna array geometries that exhibit multiband characteristics. In this paper array pattern synthesis of hexagonal fractal antenna array (HFAA) is proposed for imposing symmetric nulls in the interference directions while maintaining a reduced side lobe level (SLL) using a modified invasive weed optimization algorithm (MIWO). The desired characteristics are obtained by optimizing the current amplitude coefficients of HFAA. Further multiband characteristics of the fractal array are investigated. The results indicate the improved performance of MIWO when compared to conventional invasive weed optimization algorithm (IWO) in achieving the desired radiation characteristics. Also optimized HFAA demonstrates multiband behavior in achieving similar radiation characteristics.
