I now give another. This was inspired by the inaugural lecture of my colleague, Professor Peter Luh, on the occasion of his elevation to the U. of Connecticut Board of Trustee University Professorship. Many of his former student and colleague were there to celebrate the occasion and congratulating him on the honor.

It was Samuel Johnson, the famous Scottish literature scholar who apologize for writing a long letter to a friend because he does not have the time to write a short one. Short lectures and speeches are notoriously difficult to give for precisely the same reason. I have also written that a good lecture should be both understandable to the average audience but also impressive to the expert. Professor Luh in about 20 minutes and 13 slides gave just such a lecture that not only describe the difficulty of solving large scale mixed integer programming optimization problem but presented a breakthrough solution approach that is bound to win him awards in the future. I drove four hours on highways to and return to hear this talk and was amply rewarded. Next time when he is in Beijing, I’ll make sure that he give the talk again to a Chinese audience.
