As a meta-heuristic algorithm, bat algorithm (BA) is based on the characteristics of bat-based
echolocation and has been widely used in various aspects of optimization problems since it …

As a recently developed optimization method inspired by far-from-equilibrium dynamics of
self-organized criticality, extremal optimization (EO) has been successfully applied to a …

Devising ways for handling problem optimization is an important yet a challenging task. The
aims are always for methods that can effectively and quickly discover the global optimum for …

Abstract Design of an effective and efficient fractional order PID (FOPID) controller for an
industrial control system to obtain high-quality performances is of great theoretical and …

This paper presents an original and efficient PSO algorithm, which is divided into three
phases:(1) stabilization,(2) breadth-first search, and (3) depth-first search. The proposed …

Most real-world applications can be formulated as optimization problems, which commonly
suffer from being trapped into the local optima. In this paper, we make full use of the global …

Daylight illuminants are widely used as references for color quality testing and optical vision
testing applications. Presently used daylight simulators make use of fluorescent bulbs that …

Although many methods have been devised for solving optimization problems, there still a
pressing need for more effective and efficient techniques. Most of the proposed techniques …

This work focuses predominantly on unconstrained optimization problems and presents an
original algorithm (the code can be downloaded from Ref. 1), which is used for solving a …
