It may come as a surprise to some to be told that the modern digital computer is really quite old in concept, and the year 1984 will be celebrated as the 150th anniversary of the invention of the first computer the Analytical Engine of the Englishman Charles Babbage. One hundred and fifty years is really quite a long period of time in terms of modern science and industry and, at first glance, it seems unduly long for new concept to come into full fruition. Unfortunately, Charles Babbage was ahead of his time, and it took one hundred years of technical development, the impetus of the second World War and the perception of John Von Neumann to bring the computer into being. Now twenty years later and with several generations of computer behind us, we are in a position to make a somewhat more meaningful prognosis than appeared possible in, say 1948. We can only hope that we will not be as far off actuality as we believe George Orwell to be, or as far off in our time scale as were Charles Babbage and his almost equally famous interpreter, Lady Lovelace.

The third national conference promotes research in the field of AI by bringing together individuals from government, industry, and academia and by providing a published record of the conference as proceedings.

The award will be presented at the Eighth International Joint Conference on Artificial Intelligence, to be held in Karlsruhe, West Germany, from 8 to 12 August, 1983. The IJCAI Distinguished Service Award was established in 1979 by the IJCAI Trustees to honor senior scientists in artificial intelligence for contributions and service to the field during their careers. The Award carries a stipend of $1,000 and covers expenses of the recipient's attendance at IJCAI. This will be the second IJCAI Distinguished Service Award; the first was presented to Bernard Meltzer in 1979. Arthur Samuel is one of the pioneeers in AI.

The basic thesis put forth in this article is that a problem solver is essentially an interpreter that carries out computations implicit in the problem formulation. A good problem formulation gives rise to what is conventionally called a strong problem solver; poor formulations correspond to weak problem solvers. Knowledge-based systems are discussed in the context of this thesis. We also make observations about the relationship between search strategy and problem formulation.

Minutes of the Third Annual Meeting of the American Association for Artificial Intelligence

The Fairchild Laboratory for Artificial Intelligence Research (FLAIR) was inaugurated in October, 1980, with the purposes of introduction AI Technology into Fairchild Camera and Instrument Corporation, and of broadening the AI base of its parent company, Schlumberger Ltd. The charter of the laboratory includes basic and applied research in all AI disciplines. Currently, we have significant efforts underway in several areas of computational perception, knowledge representation and reasoning, and AI-related architectures. The current computational environment includes several large mainframes dedicated to AI research, a number of high-performance personal scientific machines, and extensive graphics capabilities.

These are the voyages of the MIT Artificial Intelligence Laboratory, and these remarks may help to understand the context of this collection, though in many ways the memoranda speak quite clearly for themselves and my comments are not, in any case, to be regarded as history, for I have written them quite hastily, in much the same spirit of the memos themselves, when it was our strategy in those early days to be unscholarly: we tended to assume, for better or for worse, that everything we did was so likely to be new that there was little need for caution or for reviewing literature or for double -checking anything. As luck would have it, that almost always turned out true.

This paper argues for the position that experimental human studies are relevant to most facets of AI research and that closer ties between AI and experimental psychology will enhance the development of booth the principles of artificial intelligence and their implementation in computers. Raising psychological assumptions from the level of ad hoc intuitions to the level of systematic empirical observation, in the long run, will improve the quality of AI research and help to integrate it with related studies in other disciplines.

Our group's work in medical decision making has led us to formulate a framework for expert system design, in particular about how the domain knowledge may be decomposed into substructures. We propose that there exist different problem-solving types, i.e., uses of knowledge, and corresponding to each is a separate substructure specializing in that type of problem-solving. This is in contrast to the currently dominant expert system paradigm which proposes a common knowledge base accessed by knowledge-free problem-solvers of various kinds. In novice, these expert structures are often incomplete, and other knowledge structures and learning processes are needed to construct and complete them.
