“…There are different techniques for selecting parent chromosomes such as roulette wheel selection, tournament selection, and reward-based selection; however the roulette wheel selection is the most commonly used technique. In roulette wheel selection technique [30], a proportion of the wheel is assigned to each chromosome based on its fitness value. The chromosomes with larger proportion are more likely to be selected.…”

This paper presents a novel hybrid metaheuristic GA-VNS matching genetic algorithm (GA) and variable neighborhood search (VNS) to the dynamic facility layout problem (DFLP). The DFLP is a well-known NP hard problem which aims at assigning a set of facilities to a set of locations over a time planning horizon so that the total cost including material handling cost and rearrangement cost is minimized. The proposed hybrid approach in this paper elegantly integrates the exploitation ability of VNS and exploration ability of GA. To examine the performance of the proposed hybrid approach, a set of instance problems have been used from the literature. As demonstrated in the results, the GA-VNS is mighty of attaining high quality solution. Compared with some state-ofthe-art algorithms, our proposed hybrid approach is competitive.

“…Bütün et al comparatively used the Newton-Raphson and the BCGA methods to minimize harmonics in the inverter voltage by optimizing the switching angles (Butun et al, 2006). Dahidah et al proposed the HRCGA to eliminate the specified harmonics while maintaining the fundamental constant and the results were compared with those obtained by the Newton-Raphson method in terms of precision and computational time (Dahidah et al, 2008).…”

“…This method, however, presents the serious drawback of having to solve nonlinear equation systems. Some efforts to simplify these systems have been made in [9][10][11][12], and soft computing strategies have been considered in [13][14][15][16][17]. Nevertheless, determining a proper initial estimate for the switching times still remains as an unsolved difficulty.…”

We present an advanced design methodology for pulse-width-modulated (PWM) DC-AC signal generation. Using design methods based on the Walsh transform, AC sinusoidal signals can be approximated by suitable PWM signals. For different AC amplitudes, the switching instants of the PWM signals can be efficiently computed by using appropriate systems of explicit linear equations. However, the equation systems provided by conventional implementations of this approach are typically only valid for a restricted interval of AC amplitudes and, in general, a supervised implementation of several equation systems is necessary to cover the full AC amplitude range. Additionally, obtaining suitable equation systems for designs with a large number of switching instants requires solving a complex optimization problem. In defining the constitutive pulses of a PWM signal, a suitable partition of the time interval is used as a reference system. In the new methodology, pulses are chosen to be symmetric with respect to the partition points, and the switching times are specified by means of switching ratios with respect to the endpoint subintervals. This approach leads to particularly simple Walsh series representations, introduces a remarkable computational simplification, and achieves excellent results in reducing the harmonic distortion.
