Cuckoo Search Algorithm for Optimization Problems

 Cuckoo Search Algorithm - Metaheuristic Optimization Algorithm

What is Cuckoo Search Algorithm?

Cuckoo Search Algorithm is a Meta-Heuristic Algorithm. Cuckoo Search Algorithm is inspired by some Cuckoo species laying their eggs in the nest of other species of birds.

In this algorithm, we have 2 bird Species.

 1.) Cuckoo birds 

 2.) Host Birds (Other Species)

What if Host Bird discovered cuckoo eggs?

Cuckoo eggs can be found by Host Bird. 

Host bird discovers cuckoos egg with Probability of discovery of alien eggs. 

If Host Bird Discovered Cuckoo Bird Eggs. The host bird can throw the egg away. Abandon the nest and build a completely new nest.

Mathematically, Each egg represent a solution and it is stored in the host bird nest. In this algorithm Artificial Cuckoo Birds are used. Artificial Cuckoo can lay one egg at a time. We will replace New and better solutions with less fit solutions. It means eggs that are more similar to host bird has opportunity to develop in the new generation and become new cuckoo. In the population, number of host nest are fixed. If host bird discovered cuckoo egg consider this worst solution that is away from optimal value.
Consider, Cuckoo Egg = New Solution.
  and        Eggs in the nest = Set of Solutions.
  and    High Quality Eggs = Best Solutions that is near to the Optimal Solution.

Three Basic Principle Cuckoo Search Algorithm Use.

1.) Each Cuckoo Lays only one Egg at a time and places it in a randomly selected nest.

2.) Best Nest with high quality of Eggs will carry over to next generation.

3.) The number of available host nests is fixed. Host bird discovers cuckoo eggs with probability 𝑷_𝒂 ϵ (0,1). Host birds can throw away the egg or leave the nest/to build a new one.

 Local Binary Pattern Introduction to Local Binary Pattern (LBP) Q. What is Digital Image? A. Digital images are collections of pixels or numbers ( range from 0 to 255).  Q. What is Pixel? A. Pixel is the smallest element of any digital image. Pixel can be categorized as Dark Pixel and Bright Pixel. Dark pixels contain low pixel values and bright pixels contain high pixel values. Q. Explain Local Binary Pattern (LBP)? A. Local binary pattern is a popular technique used for image processing. We can use the local binary pattern for face detection and face recognition. Q. What is LBP Operator? A. LBP operator is an image operator. We can transform images into arrays using the LBP operator. Q. How LBP values are computed? A. LBP works in 3x3 (it contain a 9-pixel value ). Local binary pattern looks at nine pixels at a time. Using each 3x3 window in the digital image, we can extract an LBP code. Q. How to Obtain LBP operator value?  A. LBP operator values can be obtained by ...

Image
There are about 1000 species of Bats. Bat Algorithm is based on the echolocation behavior of Micro Bats with varying pulse rates of emission and loudness. All bats use echolocation to sense distance and background barriers.  Microbats are small to medium-sized flying mammals. Micro Bats used a Sonar that is known as Echolocation to detect their prey. Bats fly randomly with the velocity at the position with a fixed frequency and loudness for prey.  Q. Whats is Frequency? A. Frequency is the number of waves that pass a fixed point in unit time. Wavelength is the minimum distance between two nearest particles which are in the same phase. Here, Sound waves are used by microbats to detect prey.  Q. What is Position? A.
