Bell Labs pages from long ago
This page mirrors some of the information
that used to be on my Bell Labs site.
Much of it is very dusty indeed.
Awk is now hosted at
An Efficient Heuristic Procedure for Partitioning Graphs
(Bell System Technical Journal, February, 1970).
An Effective Heuristic
Algorithm for the Travelling-Salesman Problem
(OperationscResearch, March, 1973).
Why Pascal is Not My Favorite Programming Language (April, 1981).
WiSE - A Wireless System Engineering Tool,
an application of computational geometry, optimization
and visualization to wireless.
Experience with Tcl/Tk for Scientific and Engineering Visualization,
programming issues in the wireless work above;
a version appeared in the Tcl/Tk Workshop, Toronto, 1995.
Timing Trials, or, the Trials of Timing:
Experiments with Scripting and User-Interface Languages,
with Chris Van Wyk, describes experiments to see how fast various scripting
and user interface languages,
from Awk to Visual Basic, run on a spectrum of representative tasks.
An AWK to C++ Translator,
describing an early experiment; published in the
Usenix C++ conference in 1991 but hard to find.
Information about the
AMPL modeling language
for mathematical optimization.
You can try AMPL on your own
optimization problems or examples from
the AMPL book;
the second edition was published November 2002 and is now available for
Examples from The AWK Programming Language by Aho,
Kernighan, and Weinberger as text (120KB)
or zipped (30KB).
The example code from The Unix Programming Environment
by Kernighan and Pike:
gzipped tar file;
the hoc calculator from The Unix Programming Environment
by Kernighan and Pike.
Software Tools programs
Software Tools in Pascal programs
Source for learn,
the original Unix computer-aided instruction program. This works but is
mostly of historical interest; it dates from 1979.
Algorithm animation (with Jon Bentley).
