 Optimization Engineering - Metaheuristic Optimization Algorithms

Optimization plays a very important role in science and engineering. Optimization aim is to find out the minimum or maximum value using any objective function or cost function. In optimization different Metaheuristic Algorithms are used to solve complex problems in various fields such as Engineering Problems, Medical Problems, Computer Problems, and different real-life problems that can not be solved using classical methods. Metaheuristic optimization algorithms are classified into two main categories as Single-based optimization algorithms and Population-based optimization algorithms. 

Single-based Meta-heuristic algorithms are also known as Trajectory Algorithms. Single-based metaheuristic algorithms provide the single solution in every iteration. Single-based Metaheuristic algorithm examples: Tabu Search, Guided Local Search, Iterated Local Search, Stochastic Local Search, Iterated Local Search, Variable neighborhood search, Greedy Randomized Local Search. 

Population-based algorithms provide multiple solutions in every generation/iteration. Population-based algorithms are categorized as Nature-Inspired Algorithms, Evolutionary Algorithms, and Art Inspired Algorithms.
Nature Inspired Algorithms are further sub-categorized as:
  1. Bio-Inspired Algorithms
  2. Human-Based Algorithms
  3. Physics-Based Algorithms
  4. Chemistry Based Algorithms
  5. Plant-Based Algorithms
  6. Swarm-Based Algorithms
Let try to understand one-by-one all these population-based metaheuristic algorithms. 

EVOLUTIONARY ALGORITHMS: As we know evolution means growth or development. The result of evolution is life on earth. Four billion years ago life has begun on earth. Different stages of life on earth such as Organisms, Multi-cellular Organisms, Fish, Dragonfly, Birds, Mammals, Bees, Flowers, Humans. The evolution process occurs by Natural Selection. The evolution process includes Natural Selection, Reproduction, and Mutation. Evolutionary algorithms are a sub-category of population-based metaheuristic optimization algorithms. Evolutionary algorithms include Genetic Algorithms, Genetic Programming, Evolution Strategy, Evolutionary Programming, Differential Evolution, and Biography based optimizers.  

PHYSICS BASED ALGORITHMS: Physics-based metaheuristic algorithms are inspired by physics rules. Physics-Based Algorithms include Multiverse Optimization Algorithm (MOA), Gravitational Search Algorithm (GSA), Black Hole Optimization Algorithm (BHO), Thermal Exchange Optimization, Big-Bang Big Crunch Algorithm, Water Evaporation Optimization Algorithms, Central Force Optimization Algorithm, Arithmetic Optimization Algorithm, and Optics Inspired Algorithms. 

SWARM-BASED ALGORITHMS: Swarm-based optimization algorithms are inspired by nature. Swarm-based optimization algorithms are basically inspired by birds, ants, bees, etc. Swarm based optimization algorithm includes Particle Swarm Optimization (PSO) Algorithm, Ant Colony Optimization (ACO) Algorithm, Artificial Bee Colony Optimization Algorithm (ABC), Bee Colony Optimization, Cuckoo Search Algorithm, Grey Wolf Optimization (GWO) Algorithm, Firefly Optimization Algorithm, Bat Algorithm, Whale Optimization Algorithm (WOA), Crow Search Algorithm (CSA), Dragonfly Optimization Algorithm, Grasshopper Optimization Algorithm (GOA), Harris Hawk Optimization Algorithm, Coyote Optimization Algorithm and other.

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...

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.
