Here's an idea I've been mulling over for a couple of years but have never got round to doing anything about. 1) Create a test suite of "reasonably active" position i.e. positions where there is a possibility of aggressive play but no real tactics. I'd suggest about 30 to 50 positions 2) Allow the engines to select a move for each position 3) For all engine pairs create a "measure of likeness" index. I'd suggest this could be: Likeness = Sum_For_All_Moves( iff(Engine_A_Move = Engine_B_Move, 1, 0) ) 3b) Possibly take the n'th root of this Likeness Measure, where n is the number of positions i.e. convert to the Euclidean distance between engines. It may not be necessary - I don't know 4) Use Multi-Dimensional-Scaling to plot the Likeness Matrix (also called the distance matrix) into a three dimensional cube or two dimensional plane. 5) See where the aggressive engines fall and try to create a principal component of aggression I don't know how well this would work but it would be interesting ;-) Let me know if anyone wants to try this out - I'd be interested.
