Harris Hawks Optimization Algorithm
Harris Hawks Optimization Algorithm Introduction
Harris hawks optimizer (HHO) is a nature-inspired population-based optimization algorithm. Harris Hawks Optimization algorithm is a Population-based algorithm. This algorithm mimics the Exploring, Exploiting, and Attacking strategies of Harris Hawks. Harris Hawks Optimization algorithm can be used to solve different engineering problems.
About Harris Hawk
Harris Hawk is a large medium bird and also known as Dusky Hawk. Harris Hawk hunt in cooperative groups and group size is 2 to 7 birds. Hawks Diet: Large insects, Birds, Lizards, and Mammals.
Harris Hawks Optimization Algorithm Steps-by-Step.INPUT: Population Size (N), and a maximum number of iterations (MaxT).
OUTPUT: Target Location and its Fitness Values.
Step 01: Initialize the population randomly 𝑋_𝑖 ( 𝑖=1,2,3,4,…𝑁 ).
Step 02: Check While ( (t ≥ max )Stopping Criteria is Matched or Not )
Step 03: Calculate fitness value for each hawk and Select Best.
Step 04: Set 𝑋_𝑟𝑎𝑏𝑏𝑖𝑡 as the best location for the rabbit.
Step 05: For each hawk Position: update Energy and Jump Strength.
Step 06: Exploration Phase
Step 07: Exploitation Phase
Following 2 Strategies are Followed by Hawks to detect a prey:
Step 08: Update Location Vector using 4 strategies: Soft Round-Up, Hard Round-Up, Soft round-up with progressive rapid dives, Hard round-up with progressive rapid dives.
Step 09: Return Best Rabbit Location and its Fitness Value.
How Harris Hawks Detect Prey?
Harris Hawks haunt randomly on certain cities and wait to detect prey. They check the Position of other family members and target position.
Q. How hawks will catch the prey?CASE 01: Soft round Up ( E ≥ 0.5 and r ≥ 0.5 )
CASE 02: Hard round Up ( E < 0.5 and r ≥ 0.5 )
CASE 03: Soft Round-Up with progressive rapid dives. ( E ≥ 0.5 and r < 0.5 )
CASE 04: Hard round Up with progressive rapid dives. ( E < 0.5 and r < 0.5 )
PARTICLE SWARM OPTIMIZATION ALGORITHM NUMERICAL EXAMPLE PSO is a computational method that Optimizes a problem. It is a Population-based stochastic search algorithm. PSO is inspired by the Social Behavior of Birds flocking. n Particle Swarm Optimization the solution of the problem is represented using Particles. [Flocking birds are replaced with particles for algorithm simplicity]. Objective Function is used for the performance evaluation for each particle / agent in the current population. PSO solved problems by having a Population (called Swarms) of Candidate Solutions (Particles). Local and global optimal solutions are used to update particle position in each iteration.

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 a
Particle Swarm Optimization (PSO) is a p opulation-based stochastic search algorithm. PSO is inspired by the Social Behavior of Birds flocking. PSO is a computational method that Optimizes a problem.

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 using the simp
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. Q. What is pulse rate? A. Wave or vibration. In th
Grey Wolf Optimization Algorithm (GWO) Grey Wolf Optimization Grey Wolf Optimization Algorithm is a metaheuristic proposed by Mirjaliali Mohammad and Lewis, 2014. Grey Wolf Optimizer is inspired by the social hierarchy and the hunting technique of Grey Wolves. What is Metaheuristic? Metaheuristic means a High-level problem-independent algorithmic framework (develop optimization algorithms). Metaheuristic algorithms find the best solution out of all possible solutions of optimization. Who are the Grey Wolves? Wolf (Animal): Wolf Lived in a highly organized pack. Also known as Gray wolf or Grey Wolf, is a large canine. Wolf Speed is 50-60 km/h. Their Lifespan is 6-8 years (in the wild). Scientific Name: Canis Lupus.
