This volume gives the proceedings of ISAAC '92, the Third International Symposium on Algorithms and Computation, held in Nagoya, Japan, December 1992. The first symposium was held in Tokyo in 1990, as the first international symposium organized by SIGAL (Special Interest Groupon Algorithms in the Information Processing Society of Japan) to serve as anannual international forum in Asia for researchers in the area of algorithms. The second symposium was held in Taipei, Taiwan in 1991, where it was decided that computation would be included in the main scope of the symposium and that ISAAC would be its name. ISAAC '92 focuses on topics in design and analysis of algorithms, computational complexity, and theory of computation, including algorithms and data structures, parallel/distributed computing, automata and formal languages, probabilistic/approximation algorithms, computability and complexity, term rewriting systems, and computational geometry. The volume contains the accepted contributed papers and the invited papers.

This book constitutes the thoroughly refereed proceedings of the 15 International Symposium on Stabilization, Safety and Security of Distributed Systems, SSS 2013, held in Osaka, Japan, in November 2013. The 23 regular papers and 12 short papers presented were carefully reviewed and selected from 68 submissions. The Symposium is organized in several tracks, reflecting topics to self-* properties. The tracks are self-stabilization, fault tolerance and dependability; formal methods and distributed systems; ad-hoc, sensors, mobile agents and robot networks and P2P, social, self-organizing, autonomic and opportunistic networks.
