\viewkind4\uc1\pard\f0\fs20 Dear Editor,\par
\par
I am a junior at the University of Pennsylvania. I would like to submit \par
an article for the RHIT Mathematics Journal Spring 2003 issue.\par
\par
The paper, "Quadratic Assignment Problems (QAP) and its Size Reduction \par
Method", was written in March 2002, when I was a sophomore at Penn. This \par
work was supervised by Dr. Peter M. Hahn. I will forward his email \par
letter to you in another email.\par
\par
Below is a paragraph describing myself:\par
\par
I am a junior at the University of Pennsylvania, concentrating in \par
Statistics and Finance and majoring in Electrical Engineering. This work \par
was from a research of Dr. Hahn, who was the instructor of my \par
undergraduate probability course. Having an immense interest in applying \par
mathematics and statistics to real life situations, I expressed my \par
interest in Dr. Hahn's research.\par
\par
\par
Thank you very much.\par
\par
\par
Yours sincerely,\par
\par
Darwin Choi\par

Darwin Choi was the top student in a class of almost 100 students taking engineering probability. After the course, and while he was an undergraduate, Darwin took an interest in my research. I encouraged him to write up some derivations that we did together. I supervised his efforts throughout the work and encouraged him to write a paper based on the work.\par
\par
The paper is a very good piece of writing and accurately reflects the work we did together. It should be of interest to a wide audience. It is certainly beyond the level of mathematical maturity required for a typical undergraduate homework assignment.\par
\par
The paper and the work leading to it were performed by Darwin Choi as an undergraduate.\par
\par
Sincerely yours,\par
