  • Time-Sharing LISP for the PDP-6 

    Unknown author (1968-03-01)
    This memo written in the style and convention of A.I. memo No. 116A, may be considered an addendum thereto. It should prove to be a welcome updating on the LISP system.

  • Numerical Solution of Elliptic Boundary Value Problems by Spline Functions 

    Unknown author (1968-04-01)
    A numerical method for solving linear, two-dimensional elliptic boundary value problems is presented. The method is essentially the Ritz procedure which uses; polynomial spline functions to approximate the exact solution. ...

  • Focusing 

    Unknown author (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. ...

  • Remarks on Visual Display and Console Systems 

    Unknown author (1968-06-01)
    This serves as a preliminary draft of Deluxe Picture Maintenance System, June, 1963. It is Technical Memorandum No. 1.

  • ITS 1.4 Reference Manual 

    Unknown author (1968-06-01)
    This reference manual is intended for those who have some knowledge of PDP-6 machine language and are either interested in the ITS monitor for its own sake, or who wish to write machine language programs to run under it. ...

  • CARPS: A Program which Solves Calculus Word Problems 

    Unknown author (1968-07-01)
    A program was written to solve calculus word problems. The program, CARPS (CALculus Rate Problem Solver), is restricted to rate problems. The overall plan of the program is similar to Bobrow's STUDENT, the primary ...

  • Holes 

    Unknown author (1968-08-01)
    This memo originally had two parts. The first dealt with certain deficiencies in an early version of Guzman's program, SEE. The problems have been fixed, and the corresponding discussion has been dropped from this ...

  • Producing Memos, Using TJ6, TECO and the Type 37 Teletype 

    Unknown author (1968-09-01)
    This memo describes the TJ6 type justifying program, which can be used in the production of memos, such as this one. In addition, sections III and IV of this memo contain related information about TECO and the type ...

  • Description and Control of Manipulation by Computer-Controlled Arm 

    Unknown author (1968-09-01)
    The immediate purpose of the research on Intelligent Automata is to have an autonomous machine able to understand uncomplicated commands and to manipulate simple objects without human intervention. This thesis is concerned ...

  • Recognition of Topological Invariants by Modular Arrays 

    Unknown author (1968-09-01)
    In this paper we study recognition of topological invariant properties of patterns by use of finite, rectangular 2-dimensional, interactive arrays of finite state automata (hereafter called modular arrays). The use of ...

  • MIDAS 

    Unknown author (1968-10-01)
    The MIDAS linking loader is a PDP-6 program to load relocatable-format output from the MIDAS assemblers, with facilities to handle symbolic cross-reference between independently assembled programs. Although it is arranged ...

  • Linear Separation and Learning 

    Unknown author (1968-10-01)
    This is a reprint of page proofs of Chapter 12 of Perceptrons, M. Minsky and S. Papert, MIT Press 1968, (we hope). It replaces A.I. Memo No. 156 dated March 1968. The perceptron and convergence theorems of Chapter 11 are ...

  • PEEK and LOCK 

    Unknown author (1968-11-01)
    This memo describes two small utility programs that are of assistance in using the ITS 1.4 (see A.I. 161, MAC-M-377) time sharing system. LOCK performs miscellaneous utility functions while PEEK displays, with periodic ...

  • Computer Recognition of Three-Dimensional Objects in a Visual Scene 

    Unknown author (1968-12-01)
    Methods are presented (1) to partition or decompose a visual scene into the bodies forming it; (2) to position these bodies in three-dimensional space, by combining two scenes that make a stereoscopic pair; (3) to ...

  • Decomposition of a Visual Scene into Three-Dimensional Bodies 

    Unknown author (1969-01-01)
    The program described here takes as its input a collection of lines, vertices and surfaces describing a scene, and analyzes the scene into a composition of three-dimensional objects. The program does not need to know the ...

  • WIRElist 

    Unknown author (1969-01-01)
    This memo describes a design aid used for the automatic production of wirelists for machine or hand wiring of wire-cards.

  • Robot Utility Functions

  • Parsing Key Word Grammars 

    Unknown author (1969-03-01)
    Key word grammars are defined to be the same as context free grammars, except that a production may specify a string of arbitrary symbols. These grammars define languages similar to those used in the programs CARPS and ...

  • A Heuristic Program that Constructs Decision Trees 

    Unknown author (1969-03-01)
    Suppose there is a set of objects, {A, B,...E} and a set of tests, {T1, T2,...TN). When a test is applied to an object, the result is wither T or F. Assume the test may vary in cost and the object may vary in probability ...
