Some random HIARCS tips:
1) On PowerMacs, HIARCS runs MUCH faster if you use the
Connectix Speed Doubler utility. If you don't use
Speed Doubler, you'd be better off on a Quadra.
On three test problems, my _minimum_ speedup was four times.
2) Open applications, even in the background, can slow
things down. I found it took over 50% longer to solve
the (included) test problem with a SimpleText
document open in the background than without.
Be wary of running head to head matches on the same machine
between two chess programs - one may steal cycles more
efficiently from the other.
3) Try different monitor color depths, and see which setting
you like best for the board appearance.
4) Some solution times for "test_problem.pgn", with:
- Show Analysis = 2
- Infinite time control
(do this first - it resets the "Book" and "Brain" settings)
- Book OFF
- Permanent Brain OFF
Now pick "Swap Sides", and "Play"
The solution is White: d1-b3.
The solution time will appear below the board, with "##"
replaced by the number of seconds, as follows:
5>>21 ## d1-b3 d8-d7 f1-b5 b8-c6 g1-f3 = 20
For HIARCS 1.0 Mac ("DBL" means Speed Doubler running).
