TLDR
The Cornell Program Synthesizer demands a structural perspective at all stages of program development and its separate features are unified by a common foundation: a grammar for the programming language.Abstract:
Programs are not text; they are hierarchical compositions of computational structures and should be edited, executed, and debugged in an environment that consistently acknowledges and reinforces this viewpoint. The Cornell Program Synthesizer demands a structural perspective at all stages of program development. Its separate features are unified by a common foundation: a grammar for the programming language. Its full-screen derivation-tree editor and syntax-directed diagnostic interpreter combine to make the Synthesizer a powerful and responsive interactive programming tool.read more

Document structure and modularity in mentor
TL;DR: The current development of Mentor reflects the belief that a major component of programming is the maintenance of large documents of a varied nature: specifications, programs, manuals, progress reports, documentation, etc...

Machine vision methods for image segmentation using multiple images
TL;DR: In this article, the second image is generated such that subtraction of it from the first image emphasizes the object with respect to the background, and then the object and background are combined to generate the final image.

Object-oriented database support for software environments
Scott E. Hudson,Roger King +1 more
TL;DR: Cactis is an object-oriented, multi-user DBMS developed at the University of Colorado that supports the construction of objects and type/subtype hierarchies, which are useful for managing the complex and highly-interrelated data found in software environments.

Closest-point problems

TL;DR: The purpose of this paper is to introduce a single geometric structure, called the Voronoi diagram, which can be constructed rapidly and contains all of the relevant proximity information in only linear space, and is used to obtain O(N log N) algorithms for most of the problems considered.

Geometric intersection problems

TL;DR: An O(N log N) algorithm is given to determine whether any two intersect and use it to detect whether two simple plane polygons intersect and to show that the Simplex method is not optimal.

An Optimal Worst Case Algorithm for Reporting Intersections of Rectangles
TL;DR: This paper investigates the problem of reporting all intersecting pairs in a set of n rectilinearly oriented rectangles in the plane and describes an algorithm that solves this problem in worst case time proportional to n lg n + k, where k is the number of interesecting pairs found.
