Introduction

The Jaya algorithm is a metaheuristic optimization algorithm introduced by R. Venkata Rao in 2016. It is inspired by the principle of achieving the best solution by focusing on both the best and worst solutions in the population. The Jaya algorithm is known for its simplicity and effectiveness in solving complex optimization problems.

Working Principle

Key Concepts

1. Best Solution: The algorithm utilizes the best solution found so far.
2. Worst Solution: It also considers the worst solution to guide the search.
3. Update Mechanism: Solutions are updated based on their distance from the best and worst solutions.

Mechanism

1. Initialization: Start with a population of random solutions.
2. Evaluation: Evaluate the fitness of each solution.
3. Update: Update each solution based on the best and worst solutions in the population.
4. Termination: Repeat the update process until the stopping criteria are met.

Implementation in C++

Here’s a basic implementation of the Jaya algorithm in C++:

Explanation

Initialization

The population is initialized with random solutions within defined bounds.

Evaluation

The objective function evaluates the fitness of each solution.

Update Mechanism

Solutions are updated based on their distance from the best and worst solutions in the population.

Termination

The algorithm terminates after a predefined number of iterations.

Conclusion

The Jaya algorithm is a simple yet effective optimization technique that utilizes the best and worst solutions to guide the search process. Its ease of implementation and effectiveness in finding optimal solutions make it a valuable tool for solving complex optimization problems.
