Conor Ryan is Associate Professor of Machine Learning at the University of Limerick where he is director of the Biocomputing and Developmental Systems Group. His background includes the development of Machine Learning algorithms and their application to industrial scale problems such as medicine and microelectronics, and he holds several patents in the area of non-volatile memory. He was previously a Fulbright Scholar in the Computer Science and Artificial Intelligence Lab at MIT in 2013 and is also CTO of software at NVMdurance, a company that uses Machine Learning to extend the endurance of Flash Memory.

Michael O'Neill holds the ICON Chair of Business Analytics at University College Dublin, and is Associate Dean - Director of the UCD Michael Smurfit Graduate Business School. He is a founding Director of the UCD Natural Computing Research & Applications Group and has over 300 publications on genetic programming, natural computing and their application in areas such as telecommunications networks, creativity, design, engineering, business analytics and finance. He has co-authored four monographs including Grammatical Evolution (2003), Biologically Inspired Algorithms for Financial Modelling (2006), Foundations in Grammatical Evolution for Dynamic Environments (2009), and Natural Computing Algorithms (2015).

J.J. Collins holds an MSc in Artificial Intelligence from Queen Mary University of London. He is lecturer in the department of Computer Science and Information Systems at the University of Limerick, and is currently working on a higher research degree in the area of Evolutionary Computation. His background includes computer vision, robotic mapping and localisation, minimisation of perceptual aliasing in reinforcement learning agents, and synthesis of algorithms using evolutionary paradigms. He was a core contributor to the design of the first Masters in Artificial Intelligence in Ireland in 2017. For J.J., the allure of the field of artificial intelligence, and the evolutionary paradigm in particular, has grown stronger over the years.

This handbook offers a comprehensive treatise on Grammatical Evolution (GE), a grammar-based Evolutionary Algorithm that employs a function to map binary strings into higher-level structures such as programs. GE's simplicity and modular nature make it a very flexible tool. Since its introduction almost twenty years ago, researchers have applied it to a vast range of problem domains, including financial modelling, parallel programming and genetics. Similarly, much work has been conducted to exploit and understand the nature of its mapping scheme, triggering additional research on everything from different grammars to alternative mappers to initialization.

The book first introduces GE to the novice, providing a thorough description of GE along with historical key advances. Two sections follow, each composed of chapters from international leading researchers in the field. The first section concentrates on analysis of GE and its operation, giving valuable insight into set up and deployment. The second section consists of seven chapters describing radically different applications of GE.

The contributions in this volume are beneficial to both novices and experts alike, as they detail the results and researcher experiences of applying GE to large scale and difficult problems.
