Introduction

Genetic algorithms (GAs) are a type of optimization technique inspired by the process of natural selection. They have been widely used in various fields, including engineering, economics, and finance, to solve complex problems. In the context of Excel, GAs can be used to optimize calculation outcomes in spreadsheets, making it an essential tool for data analysts and scientists. In this article, we will explore the concept of GA optimization for Excel, its applications, and how it differs from the built-in Solver tool.

What is GA Optimization?

GA optimization is a technique that uses the principles of natural selection and genetics to find the optimal solution to a problem. It works by creating a population of candidate solutions, evaluating their fitness, and selecting the fittest ones to reproduce. The process is repeated until a satisfactory solution is found. In the context of Excel, GA optimization can be used to optimize calculation outcomes, such as minimizing or maximizing a function, subject to constraints.
