Default Shredder704.eng analysis is nonsense!

Oh yea lets now forget how you bashed chessbase for the hiarcs posting
that
is newer than this one.....




Yes, it will by hyped as the latest Chessbase release, and probably
posted
at the top of the next SSDF list (a paid-for subsidiary of Chessbase) --
just in time for the holiday 2003 sales season. Well, that's my theory
anyway. That's how Shredder 7 as #1 happened, probably. They
conveniently
failed to match Shredder 7 vs Deep Fritz 7.0 which would probably have
knocked it further down the list.

I disagree. The Fritz engines had the same kind of problem, but they
eventually fixed it. It is indefensible for such nonsense to appear in
the
engines pane as legitimate analysis.


Who says that it's legitimate analysis? What's the authority for its
being dubbed as legitimate analysis?

It's an indication of how the engine is *working*, nothing more,
nothing less.

I've given that some thought... If there is concern about interrupting the
engine's critical algorithm in progress, slowing it down too much: One way
would be to let the GUI apply some simple universal tests (usable with any
engine) to the line of analysis before it is printed to the screen (or
output buffer), then concatenate it if a nonsense move is encountered.

I've
already mentioned some simple tests: "mate in 1", and giving away material
for free (particularly the queen). There could be a user controlled

variable
to switch this feature on/off. My guess is a 0.1% slowdown or less is
possible, which should be acceptable to all concerned. Consider that a

line
of analysis is burped out into the real world in the GUI's engine pane in
infinite analysis mode relatively infrequently. Often it takes several
minutes between those outputs, sometimes an hour or more. [That needs to

be
fixed too! Surely an updated best line of analysis should be output at

least
every 5-10 minutes, or that option offered to user.]

I think you are wrong, the deeper the search goes, the more time it takes to
evaluate a single move in a given position, because every move produces its
own tree that grows significantly (every next ply takes roughly a square
root of the number of legal moves available), so askind the engine to
produce update of the best line is nonsense, as there is no new data to
update the best line because it considered moves 5 throu 7 in that time
frame (unless move No. 5 suddenly turns out to be better, in which case the
best line is updated without asking engine to do that).

You didn't understand my line of thought. I was not asking the engine to do
anything! The GUI could have a simple "filter" that would evaluate a line of
analysis to concatenate it when a stupid blunder is found, before it is
printed out to the screen for the user to see. Of course the engine could
have a subroutine to do this also, which would be preferable. Actually the
fact that the line of analysis needs to be "filtered" indicates to me that
there is a bug in the engine itself which needs to be fixed. I guess not
everybody agrees with the latter, but I've written chess software so am not
totally ignorant of the algorithms involved, and that's my opinion at this
point. It may be that the engine has a bug in its process of storing then
outputting this analysis data to the GUI, i.e. it's simply outputting the
wrong data. It can be tricky to code right...

Hmmm. So your solution to solving world hunger would start with

Opprobrium.

It's a really big word! Look at all of those letters in a row!

Look it up! Go on...off you go!
