---------------------------------- [RULES] ----------------------------------

Unless stated otherwise in the competition specific rules, your entry must
  ... follow the competition specific rules.
  ... have the filename "entry.com".
  ... work in a Windows95 DOS box.
  ... work on the Adok's PC. an Intel Pentium 600, 64 MByte RAM,
      running Windows 98 [Version 4.10.2222].
  ... use only instructions up to i586 (Pentium).

Unless stated otherwise, your entry must NOT
  ... depend on its file name, i.e. it still has to work after renaming
      it to, say, FOOBAR.EXE, or any other valid DOS executable file name.
  ... depend on its drive or path.
  ... crash unless where explicitly stated by the rules.
  ... use MMX instructions or other non-Pentium instructions like CMOVcc;
      look at the "x86.txt" file for further information.
  ... use the special registers CR0..4 (this includes the MSW), DR0..7, or 
      RDMSR/WRMSR instructions.
  ... use any external files or create new files on the disk.
  ... rely on any previously loaded code or data in memory, excluding
      DOS itself.
  ... disable interrupts for longer than 1/50 second in a row on
      a 200MHz Pentium.
  ... have been modified by means of an executable-packer (i.e., entry.com
      must be the product of assembling entry.asm).

You may assume that
  ... the registers have these values (all in hex):
      (xx - means an unknown value which MUST NOT be assumed)

          EAX = xxxx****
                AL = 00 if first FCB has valid drive letter,  FF if not

  ... that the program is not loaded high.
  ... that DPMI services are available.
  ... FCB functions can be used to access files whose name is given in 8.3
      format.

You must NOT assume that
  ... the  FPU  state is  defined;  you have to use  FINIT  to  initialize it
      before using it.

If you use other's people code (from previous compos or the like), please
add a comment about this to your code, including a reference to the original
program. Oh yes, and please comment your code.

------------------------------ [MEMORY LAYOUT] ------------------------------

The PSP is a copy of a buffer containing the history of command line
arguments. You can assume that all preceding command line arguments were
smaller than 100 bytes. That is:
  PSP:[E5h] = 0Dh or 0
  PSP:[E6h]...[FFh] = 0

Format of Program Segment Prefix (PSP) (located at initial DS:0000):
[according to Ralf Brown's Interrupt List]

-------------------------------- [CHECKING] ---------------------------------

Usually, there is a test suite provided with the competition rules, which is
irregularily updated; new versions can be found at

                      http://www.hugi.de/compo/

However, the test suites usually only serve as a GUIDE, so please check your
program against the rules before submitting. Also be aware that the test
suite itself may contain bugs; if you find one, please send an e-mail about
it to Adok (cdvolko@gmx.net) or (preferred) to the compo mailinglist (see
below).

------------------------------- [SUBMISSION] --------------------------------

You have to send

  - the sourcecode of your entry
  - the executable of your entry ("entry.com")

to Adok so that he can analyse and evaluate your entry.

Send your entries to:
                         cdvolko@gmx.net

It would be best if you could submit your entry as early as possible. Then
Adok can inform you about bugs, if he finds any, and you have enough time to
fix them. Attention: if he finds no bugs, this doesn't automatically mean
that your entry is bug-free; see also CHECKING (above).

You can submit updates to your entries all the time till the deadline.

Entries that do not agree with these rules will be disqualified. Their coders
will be informed about the mistake, and they can re-submit a bugfixed version
unless the compo is over.

Only one entry per coder can qualify; if two or more coders work together on
a single entry, it will count as a joint entry for those coders; no other
entries of these coders can qualify. Note that the entry will count as a
entry of this group of coders for the world league table.

----------------------------- [PUBLIC JUDGEMENT] ----------------------------

After the deadline for entry submission, as soon as the entries and the beta
results are released, the public judgement starts. During this week you can
discuss and object to the entries that seem to break some rule. Please send
your objections to the compo-mailinglist (see below). Adok and/or a jury
formed by him will check if your objections are according to the rules.

If a hidden flaw is found in one of the originally accepted entries during
the public judgement period, public judgement will decide what to do with the
entry. Possible consequences include disqualification and penalties.

------------------------------- [PRE-RESULTS] -------------------------------

Preliminary results of this compo will be released on the compo-web-site and
always updated after receiving a new entry. In this way the compo will
hopefully be exciting.

Compo-web-site URL:
                     http://hugi.de/compo/

---------------------------------- [PRIZES] ---------------------------------

I'm sorry if I disappoint you, but there are no material prizes. Everything
is just a matter of fun, honor and fame. Moreover, the 30 best competitors
will get points and be listed in the 'World League Table of Assembly'
situated at the compo-web-site. Reaching a good place at a compo and even
more in the World League Table of Assembly is a good visiting-card and
recommendation for every competitor!

------------------------------ [MAILING LIST] -------------------------------

The purpose of the Hugi Compo mailing list is to inform about new compos and
provide a discussion forum for the competitors. At the moment there are about
220 subscribers.

To subscribe send a mail to hugi-compo-subscribe@yahoogroups.com. You'll get
an automatically generated mail which confirms your subscription within a few
hours. Then you start getting the mails the others have posted to this
mailinglist. You will have to subscribe to write mails to the mailinglist.

Original rules by Adok
Extended and revised by INT-E

Here is some of the math used to determine the value of the Golden Ratio.


STEP 1:

Phi can be determined using the ratios of these line segments.

                                    A
                        ------------+-------
                              B         C

        phi = A/B = B/C
              A = B + C

If we let B = 1 then we are left with two unknowns, A and C. With the two
equations, we can solve for A and C, and A = phi.

        phi = A/1 = 1/C
              A = 1 + C

        phi = 1/C
        phi = 1+C

The value of C in the second equation is:

        C = phi-1

Substituting this into the first equation gives:

        phi = 1/(phi-1)

Multiplying both sides by (phi-1):

        phi(phi-1) = 1
        phi^2 - phi - 1 = 0

The general solution for a quadratic equation is:

             -b +/- sqrt(b^2 - 4*a*c)
        x = --------------------------
                      2*a

Thus:
               -(-1) +/- sqrt(-1^2 - 4*1*(-1))
        phi = ---------------------------------
                         2*1


               1 +/- sqrt(5)
        phi = ---------------
                   2

               1 + 2.236
        phi = ----------- = 1.6180
                   2


               1 - 2.236
        phi = ----------- = -0.6180
                   2

Since phi = A, and a line segment doesn't have a negative length, we
choose the first answer.


STEP 2:

Now we have an equation for computing phi:

               1 + sqrt(5)               sqrt(5)
        phi = -------------   =   1/2 + ---------
                   2                       2

The only "little" problem is how do we compute the sqrt(5) to a few
thousand places? The FPU only provides about 16 decimal places.

The answer is we use a Taylor's series expansion, which uses only
4-function arithmetic. We can write routines that do this arithmetic with
(essentially) unlimited precision.

Doing a bit of algebra converts the above equation into a form suitable
for Taylor:

        phi = 1/2 + (1 - 1/5)^-.5

The general solution to the second term can be looked-up in a handbook:

                     n(n+1)x^2      n(n+1)(n+2)x^3      n(n+1)(n+2)(n+3)x^4
(1-x)^-n = 1 + nx + ----------- + ----------------- + ---------------------- +
                        2!               3!                     4!

Thus:
                          .5(.5+1).2^2     .5(.5+1)(.5+2).2^3
(1-.2)^-.5 = 1 + .5*.2 + -------------- + -------------------- + ...
                               2!                 3!

This certainly seems like a step in the wrong direction. Things are
getting MUCH bigger rather than smaller. However note that there is a
pattern to the terms in the expansion. Each is equal to the previous
one times (n+i)x/(i+1). For example when i=2 the term is:

        n(n+1)x^2 / 2! * (n+2)x/(2+1) = n(n+1)(n+2)x^3 / 3!


STEP 3:

The example program uses another trick called the spigot algorithm. This
computes the digits three at a time. The algorithm is tricky and best
explained by its discoverers:

                             The Golden One

This time your task is to create the world's smallest program that
displays the Golden Ratio. This is the ratio of dividing a line segment A
into two parts B and C such that A is to B as B is to C.

                                    A
                        ------------+-------
                              B         C

This deceptively simple ratio has fascinated mathematicians for centuries.
It can be written as A/B = B/C.

The ratio A/B is usually designated by the Greek letter phi, and it is
approximately equal to 1.618.

Now if your task were to simply output "1.618", it wouldn't be much of a
challenge. Printing a text string would do. The challenge is that your
entry must print the value of phi for 2400 places after the decimal
point, rounded to the nearest value. You may use a text string if you
want, but it's very unlikely to be a winning strategy.

So that an automated tester can be used to check your program, it must
output the digits to the standard output device (stdout). The exact
format must be: "1.618...<cr><lf>" with, of course, the dots being
replaced by the proper digits.

Your program must be called "entry.com".

In case these rules aren't crystal clear, and to give you a giant hint
for a great algorithm, an example program is provided (example.asm).

To help verify that you haven't overlooked some nasty little detail, a
test suite is provided. Simply run test.bat.

Send your entry.com file along with its source code to Sniper at:

        ------->>  fys@frontiernet.net <<-------

The compo deadline is May 31, 2006 at midnight (Mountain Standard Time).

You may enter as often as you want until the deadline (in fact you are
encouraged to do so to add to the excitement of the compo).

To avoid putting too much burden on Sniper, your entry must complete the
test suite in less than 5 minutes on his computer.

Besides these rules, you must follow the general rules that apply to all
compos (see general.txt).
