Learn Grey Wolf Optimizer Step-by-Step using examples in Hindi. Video Chapters: Grey Wolf Optimizer 00:00 Introduction 00:47 Topics Covered 01:28 Grey Wolf Real-life Behavior 04:35 GWO Simulation 09:36 GWO Step-By-Step 16:50  GWO Applications 17:07 GWO Advantages 17:22 GWO Disadvantages 17:29 Conclusion Grey wolves, in the wild, have a natural ability to locate prey and encircle it during a hunt. This process is led by the alpha wolf , with occasional help from the beta and delta wolves . The remaining wolves (omegas) follow the leaders' guidance. In optimization problems, however, the location of the optimal solution (the "prey") is unknown. To mimic this behavior in the Grey Wolf Optimizer (GWO), we make some assumptions: Alpha, beta, and delta are considered the top three best solutions found so far. These three "leader wolves" guide the movement of all other solutions (search agents or omegas). Grey Wolf Optimizer (GWO) is directly inspired by the social ...

Crow Search Algorithm (CSA) / Crow Search Optimization (CSO) Algorithm

Image
What is the Crow search algorithm? Crow search algorithm (CSA) is a population-based algorithm. Crow search algorithm is similar to Particle Swarm Optimization (PSO) algorithm. Crow search algorithm mimics the crow's intellegent behavior. CSA is based on crow's intelligent behavior.  Key Point About Crow's Crows live in large families and care for younger ones. They eat insects, worms, nuts, fruits, food, birds, non-insects, etc. They can hide excess food in hiding places and retrieve it when needed. Age: 14-17 years. Crow can memorize the hiding place positions. They follow each other to steal their food. Crows protect their hiding places from attackers. Two main parameters used in the CSA algorithm : Flights Length, Awareness Probability.  Crow Search Optimization Algorithm Main Concepts  Crow store excess food in hiding places and retrieve it when needed.  Crow cheat each other (i.e., they steal each other food). Crow Search Algorithm Step-by-Step with Example ~x...

Cuckoo Search Algorithm for Optimization Problems

Image
 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...

Particle Swarm Optimization (PSO)

Image
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. PSO searches for Optima by updating generations. It is popular is an intelligent metaheuristic algorithm.  In 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. After a number of iterations agents / particles will find out optimal solution in the search space. Q. What is PSO? A. PSO is a computational method that Optimizes a problem. Q. How PSO will optimize? A. By Improving a Candidate Solution. Q. How PSO Solve Problems? A. PSO solved problems by having a Population (called Swarms) of Candidate Solutions (Particles). Local and global optimal solutions are used to ...

Information Security Law and legal Framework

Image
Information Security means Data Protection. Information Security Laws deal with Creating, Storing, and Acquiring Information. Q. What is the Indian IT Act? A. It is an Act of the Indian Parliament. This is Law in India that deal with Cyber Crimes and Electronic Commerce.  Cyber Crime: [IT Act 200] Crime that involves computers and Networks. Cyber Crime involves crimes related to Computers. For Example-  Theft and Hacking.   Privacy Concerns Involved in Cyber Crime:  - Data/Information Privacy  - Financial Theft/Frauds Related Crimes  - Online Harassment - Online transaction Frauds    Q. What is a Patent Law? A.  It is the branch of  intellectual property law. Patent law deals with new scientific inventions. Patent Law in India starts in 1911.  Q. What is a Copyright Law? A . Law for copyright protection. Copy right law protects the original work of the creator. This law provides protection to sound recording, musical work, ar...

3D Translation Example

Image
 Consider the effect of a translation in the x,y,z direction by -2, -4, and -6 respectively on the homogenous coordinate position vectors [1, 6, 4].  Solution. 3D Translation Matrix is given as: Here, Tx = -2, Ty = -4, and Tz = -6. As We know, 3D translation is performed as: Therefore, we got  New co-ordinates are [-1  2  -2 ]

Three Dimensional Transformations and Viewing

 Three Dimensional Transformations  Q. What is 3D Translation? A. Translation means shifting a point or moving the whole object. In 3D we need 3 Translatio factors. Translation Matrix for 3D:  Q. How to perform 3D Transformation? A.  To perform 3D Transformation. Multiply point with translation Matrix. Here, Q. What is 3D Scaling? A. Scaling changes the size of the object. Scaling in 3D is similar to scaling in 2D. The Matrix for 3D scaling transformation given as:
