That depends on the software with which you read the newsgroup,
I read it in UNIX with something called "nn", but let that go.
We're not accusing you of being intentionally difficult, you
will admit that you have way more time to craft posts than I
do and way more time to read them, I've not read most of your
longer posts completely and freely admit that.

You can "know" Allan pretty well by reading his articles:

http://www.diplomacy-archive.com/resources/articles_by_allan.htm

See especially the article "A Dozen Years of Diplomacy".... Stephen
Agar sometimes reads this newsgroup, note his comments in editing
that article. Some of the "confusion" arises BECAUSE Allan needed
a lot of editing. But still, the key point is that A.B.C. almost
never writes about these kinds of finer points except to say
that he tried to get all the consistency stuff worked out so
they could get on with the Diplomacy.... and trying to sneak
Flying Dutchmen onto the board....

I am no more in the know on that than anyone here and we
all assure you on THAT issue, Randy is not basically right,
he's completely right.

Again, don't try to slide "minority/majority" to "insider/outsider".
It isn't helping. There are tens of thousands of Diplomacy players
worldwide and we all play the game almost entirely the same way
as far as adjudication goes. Every once in a while we find a
small hobby sub-group that plays with some strange rule interpretation,
but these days that's pretty rare.

Hi,

I've removed most of my articles from my web site and have substituted
the
following text (though most of my articles are still, I believe, in
this newsgroup):

--------------------------------------------------------------------
Almost everyone plays Diplomacy in an identical fashion. My articles
that were
here would, perhaps, add unnecessary confusion and have been removed as
they
were an exploration of the rule book or rule books, and my
interpretation was
different from how almost everyone plays Diplomacy. In short, almost
everyone
plays Diplomacy as described by the DATC.

Presumably, although I have yet to ask this question in the newsgroup,
the
way everyone plays Diplomacy is how the game designer intended. If
this is so,
then this demonstrates a clear intent, and is important in and of
itself,
regardless of how one might interpret the rule book or rule books.
--------------------------------------------------------------------

So, I'd like to ask my last related qustion or two.

Question 1
-------------
For those who know, does the way that almost everyone plays
Diplomacy at this time reflect the original game designer's
intentions? I suspect the answer is yes due to the following
reasoning: if almost everybody plays by the interpretation
of the DATC, then this must include game designer also.

Question 2
-------------
Are there any historical games that I could look at
in which the original game designer particpated in?
Thanks in advance.

Hi,

Thanks for the input Lucas. Concerning my terminology
about "almost everyone" I meant with respect to the issues
I have misinterpreted, that is, concerning the issues I
have misinterpreted, almost everyone agrees that I have
mis-read the rule book or rule books. Sorry for any confusion.


I now have a simpler question.

Question 3
---------

I realize that the rules of Diplomacy have
undergone change and development over
time.

I would like to see the moves that occurred
in the first diplomacy snail-mail games either
in the UK or the USA, or both.

So, how would I do this? Would I subscribe
to which "zine," or would I talk to a publisher
of a "zine" and say that I wish to purchase
the first 10 snail-mail games that are currently
stored on record.

Thanks everyone.

The game designer (Calhamer) has rather strange view on rules.
If you look how talks about it, it is more that he discovers the
rules then invent the rules. So, it is difficult to talk about
the designer's intentions.

Hi Lucas and everyone,

I can understand where he is coming from. With a relatively
simple set of movement rules, the situation gets very complex
very quickly.

In a sense, I'd say that the game creator has an open mind,
and he's constantly rediscovering his game while he thinks
about it; this is just my guess based upon your statement.
It probably shows he is very creative.

Cheers

Hi Randy and Jim and Everyone,

This issue for this thread has finally been
resolved such that I now have evidence
of the game designer's beliefs.

See this topic in the news group:

http://groups-beta.google.com/group/rec.games.diplomacy/browse_frm/thread/26d5be3ab59bb3bb/ec57710e4833169f?_done=%2Fgroup%2Frec.games.diplomacy%3F&_doneTitle=Back+to+topics&_doneTitle=Back&&d#ec57710e4833169f

Jim pointed me to the article, and I was
able to deduce from there.

Thanks

ANd that's good, the discussion has been good from that perspective.

Nobody wants ambiguity, did you read what he wrote about
these questions? But the practicality was first.

That's right.

> In short, almost everyone plays Diplomacy as described by the DATC.
The DATC is the result of an intensive study on rulebooks, houserules
and discussion in varies forums.

It is not true that everyone plays Diplomacy in the same way. The
disputable items are listed in chapter 4. The most disputable items
are 4.B.4 and 4.E.1. For those issues there are really two groups
and I even failed to determine which is the majority view and which
is the minority view.

For issues not listed in chapter 4, it is very likely that it is not
disputed. Just try to find a test case which such situation and look
to the explanation.

The game designer (Calhamer) has rather strange view on rules.
If you look how talks about it, it is more that he discovers the
rules then invent the rules. So, it is difficult to talk about
the designer's intentions.

I think so. The JDip, Palmpolitik and DipTool implementations are
really different from the 'DPTG' (sequence based) family of adjudicators.

JDip and Palmpolitik use a 'random decision based' adjudicator. Take
the equations I posted earlier. You initialize the decisions (or variables
that are still 'unknown') to 'undecided' or 'unknown', whatever name you
like.

This is different from a sequence based algorithm, where a move succeeds
until it fails and a support is given until it is cut. Here it starts in
a state where it can go to both 'cut' or 'given', but at the moment it is 'cut' or
'given' it will remain there. Like in any equation, if a variable is known,
it will not change (in fact before it was known, it did not change, but it
was just unknown).

Then you start adjudicating orders at random (or just start at the top).
If it is possible to adjudicate the order, adjudicate, otherwise (when it
depends on orders which are still 'undecided') skip it and try later again.

Repeat until you can't do anything anymore. In that case you are finished
or you encountered a circular movement or convoy paradox. Resolve that
situation and continue until you are finished.

The DipTool algorithm is different. It uses a 'leaf decision based' algorithm.
It takes the order equations and builds a dependency graph of these equations.
It will first adjudicate the 'leafs' of the graph. That are those orders that
can be adjudicated, because they do not depend on other orders or only orders
that are already adjudicated.

It will continue adjudicating the 'leafs' of the graph. This ends when the
adjudication is finished or when there is a circular dependency. This circular
dependency does not need to be a circular movement or convoy paradox. It is
possible that this circular dependency, still has just one resolution. DipTool
will take one order out of this cycle and do a guess for this order. It then
adjudicated the other orders out of the cycle and then re-adjudicate the order
it guessed. If the result is consistent, then this is a possible resolution of
the cycle. It will do all possible guesses for the chosen order. If there is only 1
consistent resolution for the cycle, then that resolution is chosen. Otherwise,
there is a circular movement or convoy paradox and that will be resolved with
a special rule.

The 'decision based' algorithms are clearly superior to the 'sequence based'
adjudicators. At the moment there is no sequence based adjudicator or algorithm
known that does not contain at least one undisputable hard bug. The DPTG has 3
bugs. While JDip, Palmpolitik and DipTool all pass the DATC test cases.

Lucas

Hi,

When I began this thread, I was a beginner in parsing the
rule books. So, a lot of the posts I have made here can
at this time be disregarded.

A detailed examination of some of the basic dynamics
of the game are now posted in this article:

Year 2000, Fourth Edition Rule Book, and DATC 6.E.4 and 6.E.5

Explorations of the 1958 and 1959 and 1961 rule books are
given in this article:
Rule Clarification by Calhamer in His Article

Thanks
