Evolutionary Computing is a research area within computer science. As the name suggest, it is a special flavour of computing, which draws inspiration from the process of natural evolution. The fundamental metaphor of evolutionary computing relates this powerful natural evolution to a particular style of problem solving – that of trial and error.
An Improved Iterative Method for Solving General System of Equations via Gene...Zac Darcy
Various algorithms are known for solving linear system of equations. Iteration methods for solving the
large sparse linear systems are recommended. But in the case of general n× m matrices the classic
iterative algorithms are not applicable except for a few cases. The algorithm presented here is based on the
minimization of residual of solution and has some genetic characteristics which require using Genetic
Algorithms. Therefore, this algorithm is best applicable for construction of parallel algorithms. In this
paper, we describe a sequential version of proposed algorithm and present its theoretical analysis.
Moreover we show some numerical results of the sequential algorithm and supply an improved algorithm
and compare the two algorithms.

3. Introduction to Genetic Algorithm
Genetic algorithm reflects the process of natural selection where the fittest individuals
are selected for reproduction in order to produce offspring of the next generation.
Used: In real-life applications such as
• data centers
• electronic circuit design
• code-breaking
• image processing and
• artificial creativity.
4. Five phases a genetic algorithm.
1. Initial population
2. Fitness function
3. Selection
4. Crossover
5. Mutation
6. Working Principle
Fitness Function: This is the function that determines the fitness of an individual.
Selection: Two pairs of individuals (parents) are selected based on their fitness scores…
8. Working Principle
Mutation: In certain new offspring formed, some of their genes can be subjected to a mutation with a
low random probability.
Termination: The algorithm terminates if the population has converged.
