Re: Cheap hardware

Some older systems need a keyboard to boot, but they may not need a keyboard to run once booted. Sometimes the BIOS can be configured to skip the boot time keyboard scan. There are keyboard plug stubs available that mimic a keyboard. Also, older keyboards (PS/2 style) are quite cheap. Most systems w...

Re: WCSAC: nineteen possible cooks

The WCSAC cook scan has now entered the 65536 second iteration. So a couple more weeks at most and let's hope for no power outages. -------- I was able to make it to the bookstore and picked up a copy of WCSAC (US$12), complete with all diagrams along with a list of answers and analysis all in EDN (...

Re: SEE on non-capture moves in main search

You can't do it all in parallel. You have to use some sort of "tree" to reduce it down to a single answer. Which is a tree of depth 6 for 64 squares... Each square could find its own answer easily, but then they have to "get together" and figure out which is the "best answer" and that adds sequenti...

Re: Fantacising about a testing cluster!

You might try connecting with a nearby school or university. They often upgrade and will auction off older machines, many or all of the same model at the same time.

Re: Fantacising about a testing cluster!

I predict you'll have a big bill for air conditioning this summer. -------- Mac OS/X has a free included distributed computing framework called Xgrid and a number have people have used this to write distributed applications designed to run on a LAN. I don't have much personal experience with this my...

Re: Kibitz score reporting in server play

When my program is playing, I want to know how well it thinks it's doing, and I want that number to look the same regardless of which color it's playing. Same thing for someone else's program. Annotation of games is a different matter. There is a long history of printed annotation and little (if any...

Re: Bounced from FICS

Make sure you seek ads for games contain the "formula" or "f" variable. Ah, I had forgotten that bit of minor arcana. I've become acclimated with the use of the "useformula" variable on ICC. Alas, with the new seeks the program is only seeing candidate counts in the low single digits. I'll have to ...

Re: Kibitz score reporting in server play

The idea of displaying a score from the program's perspective is more confusing and after a couple of years, most people decided that they liked the way Crafty displays scores. If you don't do it like this, how do you "annotate" a game with meaningful scores??? Because server play with one or two p...

Re: Bounced from FICS

For some reason, the "assesswin > 0" in the program's formula is not working. The program is still being matched to very low rated challengers. I tried "assesswin > 1" and there was no difference. -------- One idea is to equip Symbolic with a cheater detector of some kind. For example, if a supposed...

Re: SEE on non-capture moves in main search

This means that it makes sense to make some extra effort to improve the move ordering at PV nodes. You can afford to do something very expensive, because the PV nodes are very few, and have big sub-trees. I think there is great scope for improvment in this area. Most programs use the same (or almos...
