Some PDP6 LISP users have felt a need for a way to incorporate MIDAS subroutines into LISP. LISP has been changed to let you do this, using files found on the LISP SYSTEM microtape. You write a routine for LISP in much the ...

The problem is to track the motion of part of a field of view. Let us assume that the scene is a two-dimensional picture in a plane perpendicular to the roll axis. (these simplifying assumptions, of course, are a main ...

CHAR PLOT is a routine which enables one to use the CalComp plotter as a versatile output device. It is presently available as CHPLOT BIN (English CHAR PLOT) on tape MS 3. The program CHAR PLOT is normally called by a PUSHJ ...

SERVO is intended as an engineering and programming analyzing and debugging aid for use with devices connected through the input and output multiplexers to the PDP-6. Cannel numbers and values to output, as well as ...

This memo is to explain why the Artificial Intelligence group of Project MAC is developing methods for on-line tracking of human eye movements. It also gives a brief resume of results to date and the next steps.

CONVERT shares with other programming languages the circumstance that it is was easier to evaluate the language and to learn its uses if it is possible to scrutinize a representative sample of programs which effect typical ...

POLYSEG takes as input a list of dotted pairs of numbers. These pairs are assumed to be the co-ordinates of adjacent points along a single closed line. It is further assumed that the x and y co-ordinates of successive ...

As part of a larger research project in musical structure, a program has been written which "reads" scores encoded in an input language isomorphic to music notation. The program is believed to be the first of its kind. ...

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 ...

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. Many of the features, such as the display, are subject to ...

Underlined terms are included in the glossary.

This paper explains our approach to the problem of pattern recognition by serial computer. The rudimentary theory of vision presented here lies within the framework of automata theory. Out goal is to classify the types of ...

PSEG is a function of one argument--a region name which comes from REGIONLIST, as created by TOPOLOGIST. When it is done, the following data structure exists. *indicates that the data was already stored correctly when PSEG ...

In addition to the description on page 13 of AI Memo 116A LAP has the following features: Current Assembly Location Reference, Assembly Time Arithmetic, Constants, Multiple Entry Routines, and Defined Machine Operations ...

This memo describes a notion of programming language for expressing, from within a LISP system, string manipulation such as those performed in COMIT. The COMIT formalism has been extended in several ways: the patterns (the ...

Very shortly there will appear on the vision library tape a field named @IAS which is a collection of compiled SUBR"s for performing general matrix row reduction and inversions. For an array A a call (IAS A NEW N M) performs ...

(1)CHAR PLOT (see AI Memo 125) has been modified for TS. [It may be found on MS4 with the non-TS version]. The following changes should be noted: CRKBRK (now called PLTBRK in the non-TS CHAR PLOT), SUBPLT (which is ...

The following is a description of SCHEMATISE, a proposal for a program that proves very elementary theorems though the use of planning. The method is most easily explained through an example die to Black.

A central problem in the mathematical teory of computers and computation is to find a suitable framework for expressing the ececution of a computer program by a computer. Within the framework we want to be alble to provide ...

SIN and SOLDIER are heuristic programs in LISP which solve symbolic integration problems. SIN (Symbolic INtegrator) solves indefinite integration problems at the difficulty approaching those in the larger integral ...
