Cuckoo Search Algorithm with Hybrid Factor Using Dimensional Distance
Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016 This paper proposes a hybrid factor strategy for cuckoo search algorithm by combining constant factor and varied factor. The constant factor is used to the dimensions of each solution which are closer to the corresponding dimensions of the best solution, while the varied factor using a random or a chaotic sequence is utilized to farer dimensions.

Cuckoo Search Algorithm with Chaotic Maps
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 Cuckoo search algorithm is a novel nature‐inspired optimization technique based on the obligate brood parasitic behavior of some cuckoo species. It iteratively employs Lévy flights random walk with a scaling factor and biased/selective random walk with a fraction probability.

A Survey of Partition‐Based Techniques for Copy‐Move Forgery Detection
The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 A copy‐move forged image results from a specific type of image tampering procedure carried out by copying a part of an image and pasting it on one or more parts of the same image generally to maliciously hide unwanted objects/regions or clone an object.
