SCHEME is a dialect of LISP. It is an expression-oriented, applicative order, interpreter-based language which allows one to manipulate programs as data. It differs from most current dialects of LISP in that it closes ...

There are many ways of programming an actuator or effector for movement between the same two points. In the interest of efficiency it is sometimes desirable to program that trajectory which requires the least amount ...

The intelligent support system project is developing a program (COMEX) to assist a commodities expert in tasks such as interpreting data, predicting trends and intelligent noticing. Large amounts of qualitative and ...

The perception of surface luster in achromatic single view images seems to depend on the existence of regions with source-like properties. These regions are due to the interaction of specular component of the surface's ...

MacLISP provides a compiler which produces numerical code competitive in speed with some FORTRAN implementations and yet compatible with the rest of the MacLISP system. All numerical programs can be run under MacLISP ...

The internal representations of the various MacLISP data types are presented and discussed. Certain implementation tradeoffs are considered. The ultimate decisions on these tradeoffs are discussed in the light of ...

Wusor II is the second program that has been developed to tutor students in the game of Wumpus. From the earlier efforts with Wusor I it was possible to produce a rule-based expert which processed a relatively complete ...

The human visual process can be studied by examining the computational problems associated with deriving useful information from retinal images. In this paper, we apply this approach to the problem of representing ...

Vision is the construction of efficient symbolic descriptions from images of the world. An important aspect of vision is the choice of representations for the different kinds of information in a visual scene. In the ...

In the particular kind of learning discussed in this paper, the teacher names a destination and a source. In the sentence, "Robbie is like a fox," Robbie is the destination and fox is the source. The student, on analyzing ...

This is the second of a two part presentation of a model for motor control and learning. The model was implemented using a small computer and the MIT -Scheinman manipulator. Experiments were conducted which demonstrate ...

The purpose of this paper is to discuss some organizational aspects of programs using the actor model of computation. In this paper we present an approach to modelling intelligence in terms of a society of communicating ...

Symbolic evaluation is a process which abstractly evaluates an program on abstract data. A formalism based on conceptual representations is proposed as a specification language for programs with side-effects. Relations ...

Trying to capture intuitive knowledge is a little like trying to capture the moment between what just happened and what is about to happen. Or to quote a famous philosopher, "You can't put your foot in the same river ...

Computers open up new ways to think about knowledge and learning. Learning computer science should draw upon and feed these new approaches. In a previous paper called "Leading a Child to a Computer Culture" I discuss ...

Pre-Readers exhibit concepts of the English word different from those of literate adults. The inclusive word concept is primary: A word is what we call an utterance and any of its parts. Pre-Readers suffer confusion ...

The work described in this paper is part of an investigation of the issues involved in making expert problem solving programs for engineering design and for maintenance of engineered systems. In particular, the paper ...

During the summer of 1976, the Massachussetts Institute of Technology Artificial Intelligence Laboratory sponsored a Student Science Training Program in Mathematics, Physics and Computer Science for high ability ...

A Moire-like effect can be observed in dot patterns consisting of two superimposed copies of a random dot pattern where one copy has been expanded, translated, or rotated. One perceives in these patterns a structure ...

This paper discusses some student projects involving generative grammars. While grammars are usually associated with linguisitics, their usefuleness goes far beyond just "language" to make different domains. Their ...
