What Is Bio-Inspired Computing?

Bio-inspired computing refers to the use of computational models and techniques that are inspired by biological phenomena, aiming to solve complex problems through methods such as genetic algorithms, neural networks, and other optimization techniques derived from natural processes 1 .

This interdisciplinary field bridges biology, computer science, and mathematics, drawing inspiration from the remarkable efficiency, adaptability, and robustness found in natural systems 1 . Natural systems typically consist of large numbers of simple processing entities that operate in a decentralized, parallel manner. Through local interactions among participants, they achieve sophisticated global functionality—a property known as emergent behavior 1 .
