A Lindenmayer system for heat exchanger network design with stream splitting

This document provides an overview of an evolutionary algorithm approach for heat exchanger network design using Lindenmayer systems (L-systems). Specifically: - It defines an L-system called GHEN that uses symbols and rewrite rules to represent possible heat exchanger network structures. - The algorithm initializes a population based on the problem definition and applies random rewrite rules over generations to evolve potential solutions. - Phenotypes are instantiated by linking exchangers in genotypes and optimizing exchanger sizing and stream splits. The best solution found is returned.
