The composition of semantics in Algol 68
The main features of Algol 68 are explained from a semantic point of view. It is shown how the language permits the composition of values and actions, i.e. ultimately…
Using computers in higher education: past recommendations, status, and needs
Data from a survey conducted with National Science Foundation support, which was published in December 1970, is reviewed, and it is pointed out that, with regard to…
Various dispersion algorithms for the polyphase sorting procedure are examined. The optimum algorithm based on minimizing the total number of unit strings read is…
Automation of etching-pattern layout
HELP (Heuristic Etching-Pattern Layout Program) is an application program developed to computerize the tedious and error-prone although vitally important wiring design of…
On accurate floating-point summation
cumulation of floating-point sums is considered on a computer which performs t-digit base &bgr; floating-point addition with exponents in the range —m to M. An…
Algorithm 414: Chebyshev approximation of continuous functions by a Chebyshev system of functions
The second algorithm of Remez can be used to compute the minimax approximation to a function, ƒ(x), by a linear combination of functions, {Qi(x)}n0, which form a…
