This volume presents the proceedings of an international symposium on algorithms held in Taiwan in December 1991. Topics include computational geometry, graph algorithms, complexity theory, parallel algorithms, distributed computing and computational algebra.

The papers in this volume were selected for presentation at the Fourth Annual International Computing and Combinatorics Conference (COCOON'98), held on August 12-14, 1998, in Taipei. The topics cover most aspects of theoretical computer science and combinatorics related to computing. Submissions to the conference this year was only conducted electronically. Thanks to the excellent software developed by the system team of the Institute of Information Science, we were able to make virtually all communications through the World Wide Web. A total of 69 papers was submitted in time to be...
