This book constitutes the proceedings of the 12th International Workshop on Algorithms and Computation, WALCOM 2018, held in Dhaka, Bangladesh, in March 2018. The 22 full papers presented were carefully reviewed and selected from 50 submissions. The papers cover diverse areas of algorithms and computation, such as approximation algorithms, computational geometry, combinatorial algorithms, computational biology, computational complexity, data structures, graph and network algorithms, and online algorithms.

This book constitutes the thoroughly refereed conference proceedings of the 9th International Workshop on Algorithms and Computation, WALCOM 2015, held in Dhaka, Bangladesh, in February 2015. The 26 revised full papers presented together with 3 invited talks were carefully reviewed and selected from 85 submissions. The papers are organized in topical sections on approximation algorithms, data structures and algorithms, computational geometry, combinatorial algorithms, distributed and online algorithms, graph drawing and algorithms, combinatorial problems and complexity, and graph enumeration and algorithms.

This book constitutes the refereed proceedings of the 14th International Conference on Algorithms and Computation, WALCOM 2020, held in Singapore in March/April 2020. The 23 full and 4 short papers presented were carefully reviewed and selected from 66 submissions. The papers focus on algorithmic graph theory and combinatorics, computational biology, computational geometry, data structures, experimental algorithm methodologies, graph algorithms, graph drawing, parallel and distributed algorithms, network optimization.

This volume of the Texts in Algorithmics series is a collection of work by the participants and friends of London Stringology Days (LSD) and London Algorithmic Workshop (LAW) 2008, sponsored by the Department of Computer Science, King's College London. The form of this volume is that of a special issue, focussing on core computer science theory along with bringing that theory into the real world of computing via practical implementation. Contributed works research: structures in music and text, diffusion tensor imaging, compression, automata, stringology, nondeterminism, transposition networks, heuristics for NP-hard problems, and novel Crochemore Sets. We dedicate this volume to Maxime Crochemore on the occasion of his 60th birthday.
