Spin Glasses and what I did with them.

I have long been interested in spin glasses. It shares some common ground with fractals - see also the interview with Mandlebrot himself- as well as genetic programming. At this time I am putting together a course which I plan to give at San Francisco State on the applications of spin glasses to complex systems.

In 1991-2 I collaborated with people at Cannon Research using MATLAB to analyze some data of digital representations of pictures of letters. We were working on ways to filter out the noise which was introduced by the translation from the video to the digital representation. We tried various algorithms to do this including an algorithm based on spin-glasses.

In 1991 I also collaborated with people at the Stanford Business School. This involved writing APL programs to do some data transfer from a DEC machine to an HP machine and I also wrote several programs which implemented the traveling salesman algorithm for a bidding project. The idea was to apply the method of simulated annealing, used in spin glasses, to implement the traveling salesman problem (TSP) algorithm. It worked but it was rather time consuming.
