Mediocre v0.4 released

[mar]

Bit late so might not be thinking clearly , but how would B be removed before C?

Yep There is nothing like double embarassement! Sorry #2 of course it will work in all cases, average query/insert/delete in constant time in 99.9% cases (table will always be much larger than max positions stored)! Brilliant solution.

[Dr.Wael Deeb]

A much faster and optimized version is released by Master Jim than the premature one provided by the author of the engine....

[Engin]

if you an expert you can it if you want !

but you must know that a beginner having trouble to install winboard engines and escpecially to configurate the INI file.

Hi Jonatan,

I have two notes:

1. Time usage seems not optimal. Under 40 moves in 3 minutes Mediocre uses only a bit more than half the time for 40 moves, usually there is 1:20 on the clock when the time control is reached.

2. The JA compile seems not to run on my Q6600. Does it use SSE4 instructions?

Hi Gabor,

JA compile does not use any SSE instructions, but executable was compressed with Aspack. Maybe this causes a problem with your cpu.

This program will unpack it > http://www.woodmann.com/collaborative/t ... npacker%29

Select Aspack plugin when unpacking the executable.

Jim.

Hi Matthew,

Your Java version is a bit ancient. Update to 1.6 or 1.7.

Jim.

I use Mac OS X so Apple distributes Java. However my version of OS X is ancient (10.4) so it is unsupported.

Hey ho!

I don't know if you have already tried this. I did a bit of googling and found it may be possible to update your java to v1.6 >

Hi Jim,

I did as you'd advised. I've obtained a 3MB executable called mediocre-04-jet-ja.unpacked.exe. Still no GUI wants to recognize it as an UCI engine. Do I have anything else to do?
I don't understand this, all my fellow members have successfully installed the engine.
BTW, I have never heard of Aspack, let alone having a compressed file inside the compressed zip. Is that so well-known?

Cheers,

What happens when you just double-click the executable? can you type the normal uci commands into the console window ? e.g

Code: Select all

uci
position startpos
go infinite

Aspack in an file compressor known to coders and compilers much like similar program called UPX which is used to reduce executable size.

A black DOS window pops up then disappears immediately. Same with both (packed and unpacked) files.
Same when I try to run them from under Total Commander. And when I direct the output to a file, the file created is 0 in size.

Hi Jim and Gabor !

The same problem here !
With a double-click on .exe file I obtain not a console mode but only a new file : mediocre-04-jet-ja.unpacked.usg
Take a look please :



And I have on my computer Java 6 update 29. Java site says all are OK with my installation !

What to do ?
