The Association for the Advancement of Artificial Intelligence, in cooperation, with Stanford University's Department of Com-puter Science, presented the 1999 Spring Symposium Series on 22 to 24 March 1999 at Stanford University. The titles of the seven symposia were (1) Agents with Adjustable Autonomy, (2) Artificial Intelligence and Computer Games, (3) Artificial Intelligence in Equipment Maintenance Service and Support, (4) Hybrid Systems and AI: Modeling, Analysis, and Control of Discrete + Continuous Systems, (5) Intelligent Agents in Cyberspace, (6) Predictive Toxicology of Chemicals: Experiences and Impact of AI Tools, and (7) Search Techniques for Problem Solving under Uncertainty and Incomplete Information.

He has divided the the labors of a crowd of ants. Another Flake's third theme is universality: text into seven sections: (1) computation, distinguishing characteristic of emergence that very different systems can behave (2) fractals, (3) chaos, (4) complex is that it involves no single in similar ways.

AAAI is pleased to present the elected fellows for 2000: Kenneth M. Ford, Eric Grimson, Leslie Pack Kaelbling, David Poole, Jonathan Schaeffer, and Bart Selman

The KDD conference series is the primary venue for presenting and publishing the highest quality advances in the field.

In 1998, the international planning community was invited to take part in the first planning competition, hosted by the Artificial Intelligence Planning Systems Conference, to provide a new impetus for empirical evaluation and direct comparison of automatic domain-independent planning systems. This article describes the systems that competed in the event, examines the results, and considers some of the implications for the future of the field.

We hope to see you in along with one or two new developments.

We order its events and find meaning in them by assimilating them to more or less familiar narratives. Temporal A wide variety of systems were presented: 1999, at the Sea Crest Oceanfront and modal logics have been used to story generation, interactive Resort and Conference Center. The reason about time, action, and adaptive fiction (including the first public titles of the five symposia were change and to program and verify demonstration from Joseph Bates's networked systems. How can we create characters from specifications of service quality in which interactive narrative emerges? The symposium focused mainly on a single, comprehensive theoretical framework, Clark's grounding model.

The 1998 Planning Competition at the AI Planning Systems Conference was the first of its kind. Its goal was to create planning domains that a wide variety of planning researchers could agree on to make comparison among planners more meaningful, measure overall progress in the field, and set up a framework for long-term creation of a repository of problems in a standard notation. A rules committee for the competition was created in 1997 and had long discussions on how the contest should go. One result of these discussions was the pddl notation for planning domains. This notation was used to set up a set of planning problems and get a modest problem repository started. As a result, five planning systems were able to compete when the contest took place in June 1998. All these systems solved problems in the strips framework, with some slight extensions. The attempt to find domains for other forms of planning foundered because of technical and organizational problems. In spite of this problem, the competition achieved its goals partially in that it con-firmed that substantial progress had occurred in some subfields of planning, and it allowed qualitative comparison among different planning algorithms. It is urged that the competition continue to take place and to evolve.

Intelligent-agent technology is one of the most exciting, active areas of research and development in computer science and information technology today. The First Asia-Pacific Conference on Intelligent- Agent Technology (IAT'99) attracted researchers and practitioners from diverse fields such as computer science, information systems, business, telecommunications, manufacturing, human factors, psychology, education, and robotics to examine the design principles and performance characteristics of various approaches in agent technologies and, hence, fostered the cross-fertilization of ideas on the development of autonomous agents and multiagent systems among different domains.

The 2000 Association of Computing Machinery Conference on Intelligent User Interfaces (IUI -- 2000) was held in New Orleans, Louisiana, from 9-12 January. This conference occupies the currently hot area that lies midway between the traditional fields of AI and computer-human interaction (CHI). For AI practitioners, this conference represents a good venue for learning about both how to design user interfaces for AI applications and how to use AI techniques to improve the user experience with more conventional applications. This year's conference drew the largest audience yet for an IUI conference, but the conference still remains at a manageable, single-track size. A wide range of high-quality presentations, tutorials, demonstrations, and invited speakers provided a bridge between the AI and CHI communities.
