This volume presents the latest research from the 20th International Conference on Computing and Combinatorics (COCOON 2014). The proceedings contain 51 carefully selected full papers and 8 papers from a co-organized workshop on computational social networks (CSoNet 2014), chosen from a total of 110 submissions. The papers cover a broad spectrum of topics within theoretical computer science, including sampling and randomized methods, logic, algebra, automata, database and data structures, parameterized complexity, computational complexity, computational biology, computational geometry, approximation algorithms, graph theory, game theory, cryptography, scheduling algorithms, and circuit complexity.

This collection of papers represents a snapshot of research presented at COCOON 2014, indicating a focus on theoretical computer science and its applications. The breadth of topics suggests a text aimed at researchers and advanced students in fields such as algorithms, complexity theory, and computational mathematics. The inclusion of a workshop on computational social networks points to an engagement with contemporary interdisciplinary research areas.
