Creation and control of internal data bases under a Fortran programming environment
A method is described for the definition of a user's COMMON structure and the automatic generation of the necessary COMMON, DIMENSION, EQUIVALENCE, and type declarations…
Syntax-directed documentation for PL360
The language PL360, together with its phrase structure grammar, is used as a concrete basis for illustrating an idea called syntax-directed documentation. This idea is:…
Some complete calculi for matrices
A matrix calculus is introduced with the intention of developing data structures suitable for a high level algorithmic language for mathematical programming. The paper…
The nucleus of a multiprogramming system
This paper describes the philosophy and structure of a multi-programming system that can be extended with a hierarchy of operating systems to suit diverse requirements of…
Representations for space planning
Problems involving the arrangement of objects in two- or three-space where the objective function primarily consists of derivatives of the distance between objects or…
The problem of the cyclical majority is presented and some new, simulated results for 3, 4, 5, … , 40 issues and 3, 5, 7, … , 37 judges are reported.
Cubic splines on uniform meshes
A very simple procedure is presented for constructing cubic splines, periodic or nonperiodic, on uniform meshes. Arcs of two cubics suffice to construct a basis of…
Comment on multiprogramming under a page on demand strategy
It has been brought to my attention that Figure 5 in my paper [1] is not consistent with Figure 2 in the paper [2], as it was meant to be. In the former the ordinate is…
Comment on Lawler’s multilevel Boolean minimization
Lawler [1] proposed a method of multilevel Boolean minimization which is a generalization of the conventional prime implicant approach for two-level minimization. In his…
