Subject: Ruffian Became Good Quickly Through The Imagination Of The Programmer

Go up one level in this thread


Ruffian outclassed the opposition quickly and easily by abandonning the current
computer chess paradigm, and going for a new one.

It is built from off the shelf computing components selected for their speed.

When faced with a position to evaluate, it searches it's database of closely
matching positions "in memory", and gives each one a score depending on how
closely it matches the current position. In the record for the best matching
position is an evaluation function, which is not a list of formulae like
conventional programs, but a neural network, built with an "off the shelf"
neural network package. Each neural network will have been both highly trained
and tuned using a commercially available genetic algorithm program.

Hence the training of the evaluation is refined in a MASSIVELY more
sophisticated way than the evaluation of a traditional programme.

Result?

A markedly better program, built quickly, simply and easily.

Extra ingredient - imagination.
