Wang is an impressive student because he has been forced to overcome the significant challenge of a serious illness during his freshman year. When I first met Wang in my Discrete Math classhe did not appear to be anything special to me. While his exam scores were goodthey were not as high as I would now expect of him. What I didn't know then was that due to his illnessWang was attempting to take all of the difficult early mathematics courses at one timeincluding Discrete MathematicsAdvanced MathematicsLinear Algebraand Possibilities. While most students found preparing for just one set of these exams difficultWang was overwhelmed by four of them. But in the endhe achieved an impressive score on the final examwhich made me conscious of his unusual determination he demonstrates when confronting difficult challenges.

　　Mr. WangI have often talked about a variety of mathematicscomputer science conceptsproblems. During these discussionsI always found him to be delightfully intelligent. Not only does he quickly understand the conceptsproblems presented to himhe is able to analyze these problemspresent solutions. But perhaps most important is that Wang's thinking is intensely rigorous. When looking at any questionhe carefully scrutinizes itif he finds any uncertain issueshe clears them up immediately. I believe this kind of thought is essential to become an excellent computer programmer.

　　Serving as his thesis advisorI had a first-hand opportunity to observe the way in which Wang's mind works. In his senor thesisMr. Wang mainly discussed two challenging questions in regards to″ANN″。 In our books in Chinaknowledge of ANNits uses are very rare. Few people in China have studied this topicconsequentlythe materials that are available on ANN are limited. Working on this difficult projectnot only did Mr. Wang rise to the challengebut he went abovebeyond the call of duty to analyze his secondary sourcestest them for accuracy in practice. In this wayhe found mistakes in the book that we use. His diligencehard work made me extremely proud of him.
