Emperor Penguin Optimizer is a Novel Bio-Inspired Metaheuristic Algorithm which is inspired by the huddling behavior of Emperor Penguin. Penguins are Aquatic Flightless Birds. Penguins spends their 50% life on the land and 50% life in the water. Penguin largest species is known as Emperor Penguin. Both male and female emperor penguins are similar in size. Emperor penguin is the only species which use huddle for their survival in Antarcticwinter. Huddle is used as a defense against cold to survive through though Antarctic winter. Huddling is used to conserve energy and increase temperature during winter. Without Huddle they lose energy and freeze.
Four Important phases to describehuddling behavior of Emperor penguins in Emperor Penguin Optimization Algorithm:
Step 01: Generate and determine the huddle boundary for Emperor Penguins.
Step 02: Calculate temperature around the Huddle.
Step 03: Determine the distance between the Emperor Penguins.
Step 04: Find out Effective Mover and Relocate.
Emperor Penguin Optimizer Pseudocode:Step 01: Initialize the Emperor Penguins population randomly in the search space.
Step 02: Initialize all important initial parameters such as Maximum Iterations, Temperature, A, C.
Step 03: Calculate fitness values for all search agents.
Step 04: Determine the huddle boundary for Emperor penguins using:
Step 05: Calculate temperature profile (T') around the huddle using:
Step 06: Compute distance between the emperor penguins using:
Step 07: Update the position of emperor penguins.
Step 08: If any emperor penguin goes beyond the huddle boundary improve its position.
Step 09: Calculate fitness values for each search agent and update new optimal solution position.
Step 10: If stopping criteria met Stop else Goto Step 05.
Step 11: Return Best Emperor Penguins/ Optimal Solutions.

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 de...

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 ...
Grey Wolf Optimization Algorithm (GWO) Grey Wolf Optimization Grey Wolf Optimization Algorithm is a metaheuristic proposed by Mirjaliali Mohammad and Lewis, 2014.

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. A place where something or someone is located. Q. What is Velocity? A. Speed of something in a given direction. Q. What is loudness. A. Loudness refers to how soft or loud sound seems to listeners.
