MARLA is a collection of FORTRAN routines which
implements the Shannon-type-chess program with alphabeta
cutoffs occurring dynamically. Board positions
are updated incrementally. Also involved in position
analysis is a production system which models the human
chess player's advice-taking, theme, and chess learning
in a general sense. Interfacing these two sections,...
Knowledge compilation improves search-intensive problem-solvers that are easily specified but inefficient. One promising approach improves efficiency by constructing a database of problem-instance/best-action pairs that replace problem-solving search with efficient lookup. The database is constructed by reverse enumeration- expanding the complete search space backwards, from the terminal problem instances. This approach...
A cost reduction analysis is performed by coordinating
the exchange of LANDSAT (formerly ERTS) data between a CDC
3300 and a PDP8/L minicomputer. The LANDSAT data is displayed
on a 4002 Tektronix terminal by means of a grayscale output.
Large amounts of data and number manipulation are processed
in the...
The application of the least squares adjustment techniques to the
area of surveying has been considered and two computer programs
called HCONTRL and VCONTRL are developed for horizontal and vertical
control respectively. The principle of least squares is discussed
in chapter II. The observation and condition equations are compared
and...
Most measures of program complexity gauge either textual or
control flow attributes of a program. A recent addition to the field
of complexity measures, the knot metric, is a function of both these
attributes. A knot measurement reflects the degree of control-flow
tangle in a program's listing. This thesis discusses...
The methodology of structured programming has
enabled rapid progress in many areas of theoretical
computer science. Structured programs are generally
easier to debug, test, prove and analyse. The development
of these achievements into commercially viable applications
and products has been slower than expected.
The primary reason is that most of...
The paper, "On the Duality of Operating System
Structures," by Lauer and Needham [21], claims that
operating systems can be modeled as procedure-oriented or
message-oriented, and that the two models are duals of each
other. Duality, in this case, means that the models are
logically and functionally equivalent, and have...
Rapid Prototyping is a technique that has been created to alleviate some of the problems inherent in the traditional approach to software development. Various prototyping techniques currently employed are presented. The user interface aspect of system design is studied and where the benefit of prototyping user interfaces lies is shown....
The study of water movement in unsaturated soils by using appropriate
diffusion equations has attracted considerable attention in
recent years.
In this study, a numerical technique is developed for solving
a generalized, dimensionless diffusion equation by the use of a digital.
computer. Diffusivity and capillary conductivity equations derived
by Brooks...
