Subject: SSDF and Evolution of Chess engines.....

 My starting purpose was to find the relation between the strength of computer
Chess engines in comparison with human "good players" (GM's-IM's), and time.
 I wondered what the relation would be and what the diagram of it would be. So i
could have a guess of, where the strength of engines tends to go at the future,
if the obvious increasement it stays the same or is decreasing, and when it
could possibly go in the future.

 Since i don't have the appropriate data for doing such a thing, as it don't
even exist(very small number of "serious" games between computers and GM's), i
have done something that looks similar but it's way different and of a much less
value.
 I've gathered the ratings of the engines that was at first places on the SSDF
for all these years and made a graph. Unfortunately we can't really conclude
something important but anyway. The only thing perhaps we see from the graph is
that the engine strength when they play between them, taking into consideration
and the hardware evolution, is steadily increases and in fact we don't see any
decrease into this inceasement, so we can expect further improvement.
Unfortunately the graph has not the appropriate form, to show us if there is a
limit at engine's strength.
Since at 27/10/2000 SSDF have removed 100 points from their list i have done the
same to the lists before 27/10/2000 in order to have a correct graph.

Here is the data and the graph:
