Peter Pan posts


Queenmatval = 1000
rookmatval = 520
bishopmatval = 360
knightmatval = 345
pawnmatval = 100

WlightBishopScale = 315
BDarkBishopScale = 315



Although i am busy tuning values against Deep Rybka 4 and also against Houdini...
One set of values may work very well against Deep Rybka 4,but might not work well against another compile always.

It's a tricky business.One can tune against a specific engine.
So i guess i can only choose 1 set of values hehe.
anyway,still busy finding better values,but for now please use the above mentioned,as Ivanhoe B52aFx64p default values are not very well tuned against Deep Rybka 4

My second choice would be these :p against Houdini of course,but still testing...


here values are :

QueenMatVal = 980
RookMatval = 510
BishopMatVal = 350
KnightMatVal = 335
PawnMatVal = 100

WlightBishopScale = 315
BDarkBishopScale = 315

Must still test these against Deep Rybka 4 as well with these second set of values haven't done that yet,after this test i am now running against Houdini
Currently Ivanhoe is in the lead,but it is still early days...


1 Ivanhoe B 52aFx64 +30 +9/=20/-6 54.29% 19.0/35
2 Houdini 1.03a x64 4_CPU -30 +6/=20/-9 45.71% 16.0/35

No real ELO improvements form material values.. these are just random.
For very short games I will recommend high (995) queen value.

we saw improvement vrs other ivans with first values , all games vrs ham heads best to date (vrs DR 4 .....) T0.4.1 were draws which decided us to test vrs DR4 and found these new values beat it and by a good margin......that does not mean another identicaly run test will produce same results of course but " cest la vie "

btw

we do not test at less than 1+1 as we KNOW bullet and ultra fast tests such as moron kevin conducts do not allow engines to go deep so do not test them at all...toy tests by spoilt fair weather and fake comrades are at best laughable
