Yes , even I believe that there could still be possibly lot of improvements -
like in better move ordering , more restricted extensions , better qsearch ,
better eval , pruning expiriments , etc.
The advantage that you and me have is that we can try out all our ideas and
release versions which incorporate the newer ideas. If they fail - too bad ,
back to earlier versions.
For commercials - they have to make sure that nothing fails , there are no
regressions - making sure that there are no regressions is a major painful
expierence.
Also , commercials will have schedules by which time they have to release a
newer and more improved version .... this is an added pressure in this
commercial arena that amateurs dont have.
Considering that I reject lot of ideas after implementing and testing it for
weeks , it is quiet easy to imagine the pain the commercials programmers go
through !!
The number of ideas that they might be trying and rejecting since it does not
fit their program will be very very high : hence the extensive testing that they
do .....
