Combinatorial Algorithms

This book constitutes the refereed proceedings of the 34th International Workshop on Combinatorial Algorithms, IWOCA2023, held in Tainan, Taiwan, during June 7-10, 2023. The 33 full papers included in this book were carefully reviewed and selected from 86 submissions. They were organized in topical sections as follows: algorithms and data structures; algorithmicand combinatorical aspects of cryptography and information security; algorithmicgame theory and complexity of games; approximation algorithms;complexity theory; combinatorics and graph theory; combinatorial generation,enumeration and counting; combinatorial optimization; combinatoricsof words; computational biology; computational geometry; decompositionsand combinatorial designs; distributed and network algorithms; experimentalcombinatorics; fine-grained complexity; graph algorithms and modellingwith graphs; graph drawing and graph labelling; network theoryand temporalgraphs; quantum computing and algorithms for quantum computers;online algorithms; parameterized and exact algorithms; probabilistic and randomized algorithms; and streaming algorithms.
