Greetings.

A quiet week on the hill, few challengers and little or no bloodwaste; are the
players taking some holydays or just preparing new weapons for next week,
nobody can tell it.

In the newsgroup there has been some discussion about a new scoring system for
multiwarrior hills, seen the too many ties and the scarcety of strategies.
John K. Lewis decided to organize a tournament to see if a reduced process
number can bring more variety.

The tournament will use the following set up:

pmars <programs 1-10> -r 100 -p 8 -k

Mail your entries to John <jklewis@ren.us.itd.umich.edu> with a subject of :

- THE BATTLE ROYAL! -


This issue includes a first release of warrior ratings, according to the
advanced benchmark. Thanks to Scott Manley that did the job.

New warriors 6  Turnover/age rate 11%
Average age: 464 ( 424 last week, 386 the week before )
Average score: 142 ( 141 last week, 130 the week before )
The top 25 warriors are represented by 16 authors, JKW with 4, Bezzi 3,
Oversby, Marsden, van Dam and Vittuari with 2.

A very quiet week this one, but 53 challenges, no push off and no new warrior
in the hilltop, paprt new version of Walk like an Egyptian for just a moment.

Mirage 2 held King position for most time sharing the spot with Solomon,
Scanny boy, the Core Clear, Chameleon an Walk like an Egyptian. The scores are
very close, we have 5 warrior in one point, 9 in four points and 21th is at
but 11 point from the top, this with an entry score of 130 points.

Scanners and pspacers seem to be the winning strategy, even if it's rather
difficult to see a tendency in such a situation.

The Hint
Multi boot routines
by David Boeren


Welcome back to another week of Core Warrior.  This hint is about how to 
write a multi-boot routine.  We all know what a boot routine is, and probably
almost all of us use one to escape from qscanners.  Pspacers sometimes have
a little trouble though.  Pspacers really need to boot, since they are big and
take some extra time for their thinking.  The problem is that if you have a
separate 1c boot for each component it gets too big and you have to limit
yourself in the number and size of the components you can use.  You can use
looping (.5c) boots instead, but the speed lost can be dangerous.  A
multi-boot
is a boot routine that will boot ALL of your components at 1c, so you only
need to include one boot routine.  This saves a lot of space, when I applied
the multi-boot to Grilled Octopus (with 3 components) I saved 16 instructions.

Let's take a look at my standard boot routine:

boot    MOV.I      tail,     3268    ; fast boot away tail first
for 9
        MOV.I     {boot,    <boot
rof
        ADD.AB       #3,     boot    ; adjust so we split to "start"
        SPL.B     @boot,       #1    ; split to main program
        MOV.I         0,     boot    ; obliterate boot pointer

Everyone's code looks pretty much the same as this, except that I add the
instructions to erase the boot pointer.  You can replace the SPL/MOV with just
a JMP if you don't need this.  Anyway, the key feature is that we boot our
component tail-first, and then we have an unrolled loop that uses the
pre-decrement addressing to loop over the component.

A successful multiboot should have a similar structure.  The simplicity
of a for/rof loop for 1c booting is great, and the convenience of only having
one instruction holding the boot destination AND the source pointer makes it
simple to erase our boot pointer.  This should also hint to us that by
replacing this instruction we can make the routine boot from a different
source.  Here is the code I developed for my multi-boot.  The reason the
first instruction isn't in the for/rof is because pmars wouldn't accept a
label right before a for/rof block.

mboot   MOV.I     }boot,    >boot    ; Multi-boot routine
for 9
        MOV.I     }boot,    >boot
rof
boot    MOV.I       inc,    bdist    ; fast boot away tail first
boff    SUB.AB       #5,     boot
        SPL.B     @boot,       #1    ; split to main program
        MOV.I         0,     boot    ; obliterate boot pointer

You'll note it looks almost the same as before.  The key difference is that
the instruction that holds the source & dest pointers is LAST rather than
first.  Our strategy is that we want to jump into the middle of the for/rof
block at some point appropriate to the size of the component we're booting,
and for this to work the pointers have to be last.  You may also note that
we now boot head-first, but this is really just a side-effect of having the
pointers last.  I still use the same SPL/MOV to erase the boot pointer, but
you can replace these with a JMP just like in the old code.

Now, when you get ready to boot you have to do a couple things.  First, you
do a MOV to set the source pointer.  Then you do a MOV to set the correct
starting point for your component (the SUB line).  Finally, you JMP into the
middle of the for/rof block to control how many instructions you are booting.
Here is an example of the code you would use to set up the multi-boot:

shred   MOV.A #ptr-boot,     boot    ; Set component boot pointer
        MOV.A        #4,     boff    ; Adjust for starting offset
        JMP.B   mboot+3,       #1    ; Jump to multi-boot routine

You can see that the multi-boot has a maximum of 3 instructions of overhead,
but quite often is it less.  I would advise having the multi-boot default
to your most common component, this component will pay *0* instructions of
overhead.  The routine will be pre-loaded with the source pointer and the
starting offset, so all you need to do is change your labels so that
anyplace that jumped to your old boot routine jumps directly into the
rof/rof block and that's it.  This can be done very easily with an equ:

boot_stone  equ   mboot+5

Of course, any time you have another component which has the same starting
offset within the component, you can save a cycle by not reloading this value.
The number of MOV's needed for booting is the same as the size of your
largest component.  If you arrange your code so that the boot setup for your
largest component comes directly before the multi-boot routine you can save
the JMP and fall-through into it, saving another cycle.  This can always
be done, so consider it a freebie.  So, in a typical 3-component pspacer
you will have one component with 0 cycles of overhead (default component),
one component with no more than 2 cycles of overhead (fall-through to mboot),
and one component with up to 3 cycles of overhead.  That's a total of 5
cycles, divided by 3 components, means an average of less than 2 cycles per
component.  This assumes that neither of your other components has the same
boot offset as your default, or else you will save even more cycles.

Finally, let's see how you would incorporate this into YOUR code.  The multi
boot you can copy directly into your code.  Replace the SPL/MOV with a JMP
if you prefer.  Now, each component will have up to 3 lines to set up the
boot.  Here's how you find the values you need:

shred   MOV.A   #A-boot,     boot    ; Set component boot pointer
        MOV.A        #B,     boff    ; Adjust for starting offset
        JMP.B   mboot+C,       #1    ; Jump to multi-boot routine

A = pointer to the first instruction of your component
B = take the instruction you want to start execution on, how many instructions
    is it from this instruction to the last instruction?
C = sizeof(biggest_component) - sizeof(this_component)

Setting up the default component should be easy enough, just follow the
example below if you need to.

So what is the total cost and benefits of a multi-boot?  The benefit is
saving a lot of space, which can be used to add an extra component or just
beef up the ones you have now.  You could also use the extra space to put in
some more complex "brains" for switching.  The disadvantages are not too bad
in comparison.  You have to pay an overhead of 2-3 cycles per component, with
one component getting a "free ride" for 0 cycles of overhead.  You can only
have one boot_distance value to tweak instead of one per component (not
usually a big deal).  Unless your pspacer is simple and small, you can
probably improve it by switching to a multi-boot.  It's not free points, but
it opens up the opportunity to add more components, better components, more
brains, or possibly unrolling some of the loops you are currently using for
speed reasons.  Hey, maybe you can even add a couple points to your spirals!


Here's an updated version of Grilled Octopus which has been modified to use
the multi-boot system.  By doing so, I've saved 16 instructions, which could
easily be used to add a 4th component.

Advanced Benchmark Scores: Latest Update
by Scott Manley

OK this is a rundown of the Advanced Benchmark scores which I've been
compiling
on my web page (http://star.arm.ac.uk/~spm/welcome.html). Looking at some of 
the ratings (one version of Koolaid scores 5.2) you might think that there are
some bugs in the scoring algorithm but the problem appears to be with the 
warrior's code.

So far I have managed to rate all the warriors which haven't generated any 
errors in my test script and I'm now working my way through fixing some
of those errors. If anyone sees a particular program out of place then 
please send me a copy and I'll run it again, but my policy is only to stop 
compiler errors not debug peoples algorithms.
  
The list presented here is not the exact same as on my web site, I have 
removed all the factoring and sorting algorithms (Snail Sort is the Champion -
scoring 3.2), and of course the script continues with the lates batch of fixed

programs.

The advanced Wilkinson/Bezzi benchmark consists of 13 warriors, each
fighting 200 battles against the test candidate.

The test warriors are

   * Agony II - Stefan Strack
   * Blizzard - Anton Marsden
   * Frontwards v2 - Steven Morrell
   * C.I.A. - Anders Ivner
   * Gem of the Ocean - Paul Kline
   * Impfinity v4g1 - Planar
   * Jack in the Box - Beppe Bezzi
   * Leprechaun on Speed - Anders Ivner
   * Lithium - John K Wilkinson
   * Memories - Beppe Bezzi
   * myVamp v3.7 - Magnus Paulsson
   * Quiz - Schitzo

How about some statistics then, most sports have them, and ours depends on 
them.

Starting with a simple histogram of the ratings

  0-10	XXXXXXXXX
 10-20	XXXXX
 20-30  XXXXXXX
 30-40  XXXXXXXXXXX
 40-50	XXXXXXXXXXXXXXX
 50-60  XXXXXXXXXXXX
 60-70  XXXXXXXXXXX
 70-80  XXXXXXXXXXXX
 80-90	XXXXXXXXXXXXXXXXXXXXXXX
 90-100	XXXXXXXXXXXXXXXXXXX
100-110 XXXXXXXXXXXXXXXXXXXX
110-120 XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
120-130 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
130-140 XXXXXXXXXXXXXXXXXXXXX
140-150 XXXXXXXXXXXXX
150-160 XXX
160+	X

The average score works out at 91.95
and the median score is 101.0
The densest scoring region is around 121 with peak density ~7-8 warriors/point
average density being 0.64 warriors/point

% Effectiveness ratings
100% 		160.5
95%		143.4	
90%		135.9
85%		130.7
80%		125.5
75%		122.2
70%		120.5
60%		113.2
50%		101.0
40%		89.6
30%		75.0
20%		52.6
10%		33.8
 5%		16.9

I'm considering relating the scores to a percentage value which is represented
by some standardised mathematical function. Most programs will score less than
100% and the idea is to follow the introduction of new strategies with a more
easily managed number, a sort of Corewar inflation index. It will also make it
easier to relate a warriors rating to its position in the tables.

OK that's all for the moment, I've got real work to be done, there are still
similar tables for Beginners and combined Beginners/Advanced and of course 
I'm still fixing a load of warriors so that they won't be rejected. There
are a couple of other things related to benchmarks I would like to do, firstly

I'd like to be able to follow the evolution of the warriors on the hill. 
Secondly I think it would be intersting to follow the development of a couple
of newbies from the development of their first programs to becoming King of
the
Hill. (Of course it might be more productive if I spent some more time 
attempting to acieve this goal).
