Subject: Harlan Mills
Dear Colleagues,
Harlan D. Mills died at his residence in Vero Beach, FL on January 8,
1996. Dr. Mills was born May 14, 1919 in Liberty Center, Iowa and moved
to Florida from Maryland nine years ago. Dr. Mills was Professor of
Computer Science at the Florida Institute of Technology and founding
Chairman of Software Engineering Technology, Inc. of Vero Beach, FL
and Knoxville, TN. He was a member of the Trinity Episcopal Church,
John's Island Club, and Vero Beach Center for the Arts.
Surviving are his wife, Luella C. Mills, and two brothers Eldon Mills of
Orlando, FL and Orval Mills of Sun Lakes, AZ. A memorial service will be
held at noon on Thursday January 11 at Trinity Episcopal Church, Vero
Beach. The family suggests that in lieu of flowers, donations be made in
memory of Harlan to the Harlan D. Mills Scholarship Fund, University of
Tennessee, Knoxville, TN 37996; VNA Hospice, 1111 36th St., Vero
Beach, FL 32960; or the Vero Beach Choral Society, P.O. Box 2801, Vero
Beach, FL 32961.
The following paragraphs are a brief summary of Harlan's distinguished
career and productive life. It was my privilege to work with Harlan during
the last decade of his life; he was a joy to work with. The clarity and
simplicity of his approach to problem solving will be an enduring lesson.
Harlan will be missed by many friends in many circles beyond those known
to me. Please feel free to send this message on to others.

January 8, 1996
Dr. Harlan D. Mills' contributions to computer science have had a profound
and enduring effect on theory, education, and industrial practice, and his
service to the profession and the nation have magnified the impact of his
contributions manyfold. Since earning his Ph.D. in Mathematics at Iowa
State in 1952, Dr. Mills has led a distinguished career. Highlights of his
many contributions follow.
Contributions to Theory
Dr. Mills' explication of the mathematical foundations of software have
had a signal influence on the discipline. His understanding that a program
is a mathematical function enabled the application of a host of function-
theoretic principles to software development and verification. His view
of software testing as a statistical experiment enabled a scientific
approach to software evaluation and certification. He contributed his
ideas to the profession in six books and over fifty refereed articles in
technical journals.
- His function-theoretic approach to program verification was presented
in "Structured Programming: Theory and Practice" (1979), co-authored by
Linger and Witt.
- A collection of his seminal papers on chief programmer teams, top-down
design, structured programming, program correctness, and other
fundamental ideas in software engineering was published in "Software
Productivity" (1983)
- His reduction of the mathematics of specification and design to
to practice was published in "Principles of Information Systems
Analysis and Design" (1986), co-authored by Linger and Hevner.
Contributions to Education
Dr. Mills has served on the faculties of Iowa State, Princeton, New York
and Johns Hopkins Universities, the Universities of Maryland and Florida,
and Florida Institute of Technology.
- At Johns Hopkins and Maryland, he initiated one of the first American
university courses in structured programming.
- At Maryland, he developed a new two-semester freshman
introduction to computer science and textbook "Principles of
Computer Programming: A Mathematical Approach," with co-authors
Basili, Gannon, and Hamlet.
- At FIT, he developed a new freshman and sophomore curriculum for
software engineering using Ada as the underlying language with
colleagues Engle and Newman.
Contributions to Industry
Dr. Mills was an IBM Fellow and Member of the Corporate Technical
Committee at the IBM Corporation, a Technical Staff Member at GE
and RCA, and President of Mathematica and Software Engineering
Technology.
- At GE, he developed a three-month curriculum in management science
attended by hundreds of GE executives.
- At IBM, he was the primary architect of the IBM Software
Engineering Institute where thousands of IBM software personnel
were trained in the mathematical foundations of software. He later
embodied the mathematical and statistical principles for software
in the Cleanroom software engineering process.
- As founder of Software Engineering Technology, he created an
enterprise for Cleanroom technology transfer.
Service to the Nation
Dr. Mills has had an abiding interest in fostering sound software
engineering practices through federal programs.
- During the formative period of the DoD DARPA STARS Program in the
1980s, he provided fundamental concepts for development of high
quality software at high productivity.
- In 1986, he served as Chairman of the Computer Science Panel for
the U.S. Air Force Scientific Advisory Board.
- During 1974-77, he was Chairman of the NSF Computer Science
Research Panel on Software Methodology.
Service to the Profession
Dr. Mills has been a program committee member and invited speaker for
many professional conferences, and a referee for many mathematics and
computer science journals.
- From 1980-83, he was Governor of the IEEE Computer Society.
- In 1981, he was the Chairman for IEEE Fall CompCon.
- During 1975-81, he served as Editor for IEEE Transactions on
Software Engineering.
- In 1977, he was the U.S. Representative for Software at the IFIP
Congress.
- In 1975, he was the Chairman of the First National Conference on
Software Engineering.

Subject: Riccati Equation Benchmark Collection
FIRST VERSION OF CAREX AVAILABLE
CAREX is a collection of benchmark examples for the numerical solution
of continuous-time algebraic Riccati equations (CARE) of the form
T
0 = Q + A X + X A - X G X
where A, G, Q, X are n-by-n matrices and X is the desired solution
matrix. The symmetric matrices G and Q can be given in factored form
as they often occur in control theory, i.e.,
T T -1
Q = C Q0 C, G = B R B .
This collection may serve for testing purposes in the construction of
new numerical methods, but may also be used as a reference set for the
comparison of methods.
The examples can be generated via a Fortran 77 subroutine or a MATLAB
function. A postscript version of a preprint describing the benchmark
collection as well as the software is available by anonymous FTP at
ftp.tu-chemnitz.de
from the directory
/pub/Local/mathematik/Benner
The (compressed) files are
blm1.ps.Z
carex_f.tar.Z
carex_m.tar.Z
Here, blm1.ps.Z is a compressed postscript version of the
abovementioned preprint and the tar files carex_f.tar, carex_m.tar,
respectively, contain directories with the subroutines, functions,
and data files necessary to generate the benchmark examples. Both
directories also contain introductory README files.
The MATLAB codes are also available via anonymous ftp from the
MathWorks ftp site (ftp.mathworks.com). The M-files, data files, and
the README file are located in
pub/contrib/control/carex
The Fortran 77 codes are available via anonymous ftp from Netlib
(e.g., netlib.att.com, elib.zib-berlin.de). The file carex_f.tar.gz
can be found in the directory
netlib/control
Since this is an on-going project, we will greatly appreciate further
contributions of examples concerning the abovementioned CARE as well
as discrete-time and generalized AREs.

Subject: New Book on Combinatories
Russ Merris, Combinatorics, PWS Publ. Co., Boston, 1996, 367+x pages,
ISBN 0-534-95154-6
The book is intended to be used as a text for a course in
combinatorics at the junior level. The author's goal has been to
provide a tool of sufficient flexibility to be useful in a wide
variety of approaches to the subject. Following the basic foundation
in Chapters 1 & 2, the instructor is free to pick and choose the most
appropriate topics from the remaining four chapters, each of which is
independent of the other three.
The material in Chapter 3, Polya's Theory of Enumeration, is
typically found closer to the end of comparable books, perhaps
reflecting the notion that it is the _last_ thing that should be
taught in a junior level course. The author has endeavored both to
make Polya's theory more accessible and make it possible for the
topic to be addressed right after Chapter 2. It's placement in the
middle of the book is intended to signal that it _can_ be fitted in
there, not that it must be.
Contents
1. The Mathematics of Choice
2. The Combinatorics of Finite Functions
3. Polya's Theory of Enumeration
4. Generating Functions
5. Enumeration in Graphs
6. Designs and Codes
