Since Grey Wolf Optimizer (GWO) first introduction, it continues to be used extensively today, owing its simplicity, easy handling, and applicability a wide range of problems. Although there are many different GWO variants in the literature, problem that produces early convergence inefficient results have still continued emerge their variants. In order overcome drawbacks theGWO, theGWO integrat...

─ Cuckoo Search (CS) is a new met heuristic algorithm. It is being used for solving optimization problem. It was developed in 2009 by XinShe Yang and Susah Deb. Uniqueness of this algorithm is the obligatory brood parasitism behavior of some cuckoo species along with the Levy Flight behavior of some birds and fruit flies. Cuckoo Hashing to Modified CS have also been discussed in this paper. CS ...

This paper reports that bursty hot spot sizes are a key factor in causing the heavy-tail distribution of flights in human walks. A heavy-tailed distribution of flights is a signature feature of Levy walks. The data analysis based on GPS traces of human walks reveals that the sizes of a few extremely large hot spots are dominating the mean size of hot spots and they cause the bursty (i.e., long-...

Formulas are derived to compute the mean number of times a site has been visited during symmetric Levy flights. Unrestricted Levy flights are considered first, for lattices of any dimension: conditions for the existence of finite asymptotic maps of the visits over the lattice are analyzed and a connection is made with the transience of the flight. In particular it is shown that flights on latti...

This article focuses the application of Levy flight based PSO algorithm for the solution of micro grid power dispatch problems. The proposed algorithm is tested on micro grid dispatch problem consisting of wind, diesel and fuel cell plants. The effectiveness of the algorithm has been verified on a test system having distributed generation compared with the other existing techniques, considering...

The foraging movements of Iridomyrmex species of ant are observed to follow a Levy flight distribution. The movement step size is shown to be characterised by a power law distribution. This makes the movement fractal in nature, which will produce an efficient search pattern. Introduction: Levy flights are a category of random walks first devised by Paul Levy in 1937 by generalizing Brownian mot...
