Features
The TEACH system was developed at MIT to ease the cost and improve the results of elementary instruction in programming. To the student, TEACH offers loosely guided…
Experiments with the M & N tree-searching program
The M & N procedure is an improvement to the mini-max backing-up procedure widely used in computer programs for game-playing and other purposes. It is based on the…
Distributions of segment sizes measured under routine operating conditions on a computer system which utilizes variable sized segments (the Burroughs B5500) are…
On an algorithm for nonlinear minimax approximation
Certain nonlinear minimax approximation problems are characterized by properties which permit the application of special algorithms, mainly based on the exchange…
A comparison of error improvement estimates for adaptive trapezoid integration
Various simple choices of error improvement estimates for the trapezoid rule are studied to demonstrate a comparison procedure which is relatively independent of the…
A deductive question-answerer for natural language inference
The question-answering aspects of the Protosynthex III prototype language processing system are described and exemplified in detail. The system is written in LISP 1.5 and…
PDEL—a language for partial differential equations
Conventional computer methods available to solve continuous system problems characterized by partial differential equations are very time-consuming and cumbersome. A…
A number system for the permutations
A number system described here is particularly suitable for numbering the permutations. An algorithm is then presented by which the permutation associated with a number…
Another method of converting from hexadecimal to decimal
There is a simple paper-and-pencil method of converting arithmetic a hexadecimal number N to decimal.
A note on the complement of inherently ambiguous context-free languages
