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.

Machine vision systems and methods for morphological transformation of an image with non-uniform offsets

TL;DR: In this paper, a method for morphological transformation of a source image with non-uniform offsets is presented, where pixels from selected neighborhoods or regions of the source image are rearranged, or unfolded, into respective columns of an intermediate image.

A high level language for specifying graph based languages and their programming environments

TL;DR: A high level language for specifying programming environments for programming languages that are based on directed attributed graphs is described, based on using a grammar to describe the components of the graph based language and using a first-order logic based language to describe state changes in editing, execution, and animation.

Early report on encompass.

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.
