#### EUTERPE A Computer Language for the Expression of Musical Ideas

(1967-04-01)

The electronic medium has vastly increased the amount of material available to the contemporary composer. The various pieces of electronic equipment available today allow one to produce any conceivable sound; yet ...

#### Focusing

(1968-05-01)

This memo describes a method of automatically focusing the new vidisector (TVC). The same method can be used for distance measuring. Included are instructions describing the use of a special LISP and the required LISP-functions. ...

#### Estimating Stereo Disparities

(1967-02-01)

An interesting practical and theoretical problem is putting bounds on how much computation one needs to find the stereo-disparity between two narrow-angle stereo scenes. By narrow angle I mean situations wherein the angle ...

#### LISP Exercises

(1964-01-01)

The following exercises are carefully graded to mesh with the sections in Chapter I, "The LISP Language", in the LISP 1.5 Programmer's Manual. Each exercise should be worked immediately after reading the manual section indicated.

#### The Proofchecker

(1961-01-01)

The Proofchecker is a heuristically oriented computer program for checking mathematical proofs, with the checking of textbook proofs as its ultimate goal. It constructs, from each proof step given to it, a corresponding ...

#### CONVERT

(1966-06-01)

A programming language is described which is applicable to problems conveniently described by transformation rules. By this we mean that patterns may be prescribed, each being associated with a skeleton, so that a series ...

#### PDP-6 LISP

(1966-06-01)

This is a mosaic description of PDP-6 LISP, intended for readers familiar with the LISP 1.5 Programmer's Manual or who have used LISP on some other computer. Some of the newer features (e.g. the display) are experimental ...

#### Secondary Storage in LISP

(1963-12-01)

A principal limitation of LISP processors in many computations is that of inadequate primary random-access storage. This paper explores several methods of using a secondary storage medum (such as drums, disk files or magetic ...

#### A Theory of Computer Instructions

(1965-09-01)

This paper has arisen from an attempt to determine the nature of computer instructions from a viewpoint of general function and set theory. Mathematical machines, however the term is understood, are not adequate models for ...

#### Natural Language Input for a Computer Problem Solving System

(1964-03-01)

This paper describes a computer program which accepts and "understands" a comfortable, but restricted set of one natural language, English. Certain difficulties are inherent in this problem of making a machine "understand" ...
