Can some explain the following re CM6000:

1 - How does the hash table size influence the program strength?

It means the program does not search the same move over and over again, thus
wasting valuable time searching over the same things again on a move.
I think this is right ?

-------------------------------------------------------------------------------------------------------------

2 - What is is set to from the factory?

The factory setting is a 1 meg hash table

-------------------------------------------------------------------------------------------------------------

3 - Should I be changing it, and if so, how and to what?

I say change it.

Okay say for example when you log into CM6K that you create a login user called
dave.
Within you CM6K directory their will be a users directory, and within that there
will now be a directory called Dave (for the user you created)

now open up a file called dave.ini or the ini file of the user name you created.
Open it using a txt editor program. Now in that file you will come to a part
that says something like this.

[engine]
ttable_size=20
book=Mentor.OBK

Now how the hash works is like this and change this line -  ttable_size=20

ttable_size=20   is for 1 meg hash
ttable_size=21   is for 2 meg hash
ttable_size=22   is for 4 meg hash
ttable_size=23   is for 8 meg hash
ttable_size=24   is for 16 meg hash
ttable_size=25   is for 32 meg hash
ttable_size=26   is for 64 meg hash

and so on

-------------------------------------------------------------------------------------------------------------

My system is a PII 350 with 64m Ram

With your system use 16 meg Hash tables, the programmer suggests this size hash
as being the best to use, no higher. but nothing is stopping you or course.

I hope this helps
