Life in computer: simulation or reality?

Abstract

This article presents two approaches to using computers as a medium where life processes could occur. In the first approach, computers are used to simulate models of life on Earth. This includes both accurate models that increase our understanding of life phenomena, and simplified models (like artificial neural networks and evolutionary algorithms) that are successfully applied to solve real-world problems. The second approach concerns creating a computer environment that enables emergence of life. The paper demonstrates benefits of the first approach and shows some of the problems and doubts related to the second approach.
