what do you think will accrue if engine A & F have hundreds of matches when engine A (elo 4000), engine B (elo 3900) and engine F (elo 2000) are on the list; do you think engine A's elo will go up or remain same or go down when A & F have hundreds of matches and the result of A Vs. F is 200 wins, 1 loss and 10 draws for A? what's gonna be the ranking after hundreds of matches between A & F (if you know how elostats work and how the elo is calculated based on which formula, you know the answer); what's gonna be the order of engines (the ranking) from the strongest to the weakest? (I'll post the answer later, but we can find the answer before)
stockfish / 1 ply search
I found out a bug or a weird symptom for SF engines
when SF is fighting with other engines
I can pause the tourney in winboard
winboard 4.70 is convenient cuz I can pause the tourney anytime
to do something else
then when I continue (un-pause) the tourney
only SF's search depth becomes 1 ply
(only when I watch a movie or I do some other things
which are CPU or RAM intensive)
then SF loses
since it can only search 1 ply ahead
elostat can't run .doc file
I just saved a plethora of matches in .doc file
the elostat 1.3 in Arena couldn't calculate for the rating list
perhaps cuz of the format and added functions of .doc file
so I saved the pgn file with wordpad or notepad
which don't support the fancy functions
then now the elostat can run the pgn well
having matches with weak engines is not good
I found out something extroardinary about elo calculating
I think there are 2 prominent elo calculating methods
and for instance,
engines ------------------------- elo ratings
A ------------------------- 3500
B ------------------------- 3450
F ------------------------- 2600
if there are 3 engines with the repective elo ratings
currently A is the best
and B is only 50 elo behind A
and F is nowhere around A or B
what do you think will accrue if A & F have hundreds of matches?
some may think
since A will have 100 wins and 0 losses
along with 0 draws
(the actual result should be something similar
like 100 wins, 1 loss and 6 draws)
A can gain more elo
which will result in A having higher elo
some may think
no, that's not the case
since the elo diff between A & F is too large
so even if A wins hundreds of rounds over F
A can't gain elo
so A's elo will remain as it is
no elo change will occur
but the answer is actually A's elo went down a lot
so if the strong engine A fights many matches
with weak engines like F
A's elo goes down
that's what I found out
I heard bouquet is not based on ivanhoe
it is based on ippolit
that was recently on the nTCET chat box
and bouquet is fantastic!
it is on top of the tourney now!!!
opening book match(tourney)
I can't understand how opening book Vs. opening book tourney can be organized
book is something that is used by 2 engines
how one engine can use book A
while another engine can use book B?
moreover, how can we get one book is better than another book?
I don't understand how opening book tourney can be done
stronger opening book means the book only has the strongest openings hence little variety in openings?
weak opening book means the book has multifarious openings hence the book is good?
if engine A choses a move from book A
then engine B choses a move from book B
and then some
how can this go on?
how can 2 opening books fight with each other?
is it even possible?
I don't have any knowledge on this matter!
