Stereo and Perspective Calculations
(1967-09-01)A brief introduction to use of projecting coordinates for hand-eye position computations. Some standard theorems. Appendix A reproduces parts of Roberts' thesis concerning homogenous coordinated and matching of perspectively ...

EUTERPE-LISP: A LISP System with Music Output
(1967-09-01)EUTERPE (Ai memo no. 129) was designed as a "real-time music program" which would interpret music described as "voice-programs" in DDT. These voice-programs consisted of note words, description of tones to be sounded, and ...

STRING
(1967-09-01)This document describes the STRING programming language which has been implemented on the MAC Artificial Group's PDP-6 computer. In the STRING system, all objects--constants, variables, functions and programs--are ...

Decomposition of a Visual Scene into Bodies
(1967-09-01)This memorandum describes a program which finds bodies in a scene, presumably formed by 3-dimensional objects, with some of them perhaps not completely visible.

LISP Linkage Feature: Incorporating MIDAS into PDP-6 LISP
(1967-10-01)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 ...

PICPAC: A PDP-6 Picture Package
(1967-10-01)PICPAC is a program to be used for manipulating pictures of real-world scenes. It operated under ITS (the Incompatible Time-Sharing System) under control of a simple on-line command language. It includes facilities for ...
-
I/O Test
(1967-10-01)IO TEST is intended as a hardware testing and debugging aid for use with the PDP-6 and its associated input multiplexer (analog to digital converter) and output multiplexer (digital to analog converter). While all characters ...
-
A Fast Parsing Scheme for Hand-Printed Mathematical Expressions
(1967-10-19)A set of one-line text-book-style mathematical expressions is defined by a context free grammar. This grammar generates strings which describe the expressions in terms of mathematical symbols and some simple positional ...
-
A Multiple Procedure DDT
(1968-01-01)This Memo. Describes a version of DDT used as the command level of the A.I. Group PDP-6 Time Sharing System (ITS). Special features include capability to handle multiple jobs, ability to stop open read or write references ...

REEX: A CONVERT Program to Realize the McNaughton-Yamada Analysis Algorithm
(1968-01-01)REEX is a CONVERT program, realized in the CTSS-LISP of Project Mac, for carrying out the McNaughton-Yamada analysis algorithm, whereby a regular expression is found describing the words accepted by a finite state machine ...
-
CNTOUR
(1968-01-01)The CNTOUR program plots an intensity relief map of an image which is read from tape, disc, or from either vidisector camera. It is used to examine vidisector images. It may also be used as a general purpose aiming, ...

The Artificial Intelligence of Hubert L. Dreyfus: A Budget of Fallacies
(1968-01-01)In December 1965 a paper by Hubert Dreyfus revived the old game of generating curious arguments for and against Artificial Intelligence. Dreyfus hit top form in September 1967 with an explanation in the Review of ...
-
PDP-6 IAP
(1968-01-01)LAP is a LISP FEXPR (or FSUBR when compiled) which is executed primarily for its side effect??ely assembling a symbolic listing into core as a machine language subroutine. As such, it is about the most convenient and rapid ...
-
CGRU and CONG: CONVERT and LISP Programs to Find the Congruence Relations of a Finite State Machine
(1968-01-01)CRGU is a CONVERT program, CONG its literal transcription into LISP, realized in the CTSS LISP of Project MAC, for finding all the congruence relations of a finite state machine whose transition table is given as an argument. ...
-
REC/8: A CONVERT Compiler of REC for the PDP-8
(1968-01-01)REC/8 is a CONVERT program, realized in the CTSS LISP of Project MAC, for compiling RED expressions into the machine language of the PDP-8 computer. Since the compilation consists in its majority of subroutines calls (to ...
-
Functional Abstraction in LISP and PLANNER
(1968-01-01)Presented here is part of the graduate work that I am doing in the much broader area of protocol analysis (see A.I. memo 137). The goal of the function abstraction is to find a procedure that satisfies a given set of ...
-
SUBM: A CONVERT Program for Constructing the Subset Machine Defined by a Transition System
(1968-01-01)SUBM is a CONVERT program, realized in the CTSS LISP of Project MAC, for constructing the subset machine with the same behaviour as a given transition system. The program interactively collects the six items defining a ...
-
A Left to Right then Right to Left Parsing Algorithm
(1968-02-01)Determination of the minimum resources required to parse a language generated by a given context free grammar is an intriguing and yet unsolved problem. It seems plausible that any unambiguous context free grammar could ...

SARGE: A Program for Drilling Students in Freshman Calculus Integration Problems
(1968-03-01)The SARGE program is a prototype of a program which is intended to be used as an adjacent to regular classroom work in freshman calculus. Using SARGE, students can type their step-by-step solution to an indefinite ...

Linear Decision and Learning Models
(1968-03-01)This memorandum is a first draft of an essay on the simplest "learning" process. Comments are invited. Subsequent sections will treat, among other things: the "stimulus-sampling" model of Estes, relations between Perceptron-type ...
