Greetings.

The optimisation of PMARS is currently being discussed in the newsgroup at the
moment. Perhaps we will see a new version soon (even if unofficial).

Round 5 of the tournament is this week. Good luck to all involved. The top 4
players go through to the semi-finals.

Weekly age: 15 this week ( 13 last issue, 29 the week before )
New warriors: 8  Turnover/age rate 53%
Average age: 152 ( 173 last issue, 142 the week before )
Average score: 138 ( 136 last issue, 138 the week before )
The top 25 warriors are represented by 12 independent authors: Franz with 5;
Marsden with 4; Oversby and Edgar have 3; and Beppe and JKW have two.

King Report: The Machine was KOTH for the majority of the week, but when Bodge
fell off the Hill it suffered and from then on unrequited love has been the
dominant warrior. Again the imp/stones are in control.

Franz has been busy this week with 4 new/updated warriors. Bremer is finally 
back on the Hill :-) May his warrior live long and prosper. The most
significant new entry is probably Silver Talon, which is also doing very well 
on the beginner Hill.

Morrell's only Hill warrior was kicked off this week as was Macrae's. Perhaps
we will see them back in force soon.

The Hint
Random Ramblings

This week I couldn't think of anything specific to discuss so you will have
to settle for a few mini-hints I could throw together. Just a note: for those
of you who want to write a hint, send it to one of us and we will probably
put it in an issue. It's difficult for us to come up with something different 
every week, but we do the best we can with the time available.

Here is an article that Paul Kline sent to the newsgroup a while ago. I think
it's worth putting in CW for future reference.

------------------------------

>From Impfinity:

bomb&i  dat     <2667, <5334
stone&i spl     #stone&i+bstep&i+magic&i, {-650
        mov.i   bomb&i, }stone&i
        add.f   #bstep&i-1, stone&i               <---- cool
j&i     djn.f   stone&i, <i-50

Use add.f #a,b to store increments on the add line itself!
Change to add.x to put the larger increment on the b-operand
of the mov, making it a step-bomber.

---------
Want to decode an imp, but don't know whether it is 

   mov   #a,2667
or
   mov.i #2667,*0

Just point this instruction at the imp and pop that imp-step into its
b-operand:

   mov.ab  @0,@wherever

---------
Your one-shot scanner keeps attacking imp-code instead of bomber?

Changing your step from 13 to 2671 gives you an increment of 13 (3*2671=13)
and scans three times as many locations before detecting 3- or 9-point imps.

---------
Your one-shot uselessly attacks bomber decrements?  Here's a version
that penetrates right through:

wScan     add    wIncr  ,wGate   ; increment pointers
          seq    }wGate ,>wGate  ; take a look
          sne.x  *wGate ,@wGate  ; ignore single decrements

[Editor's Note: this code will also penetrate through the last instruction of 
a warrior, but to do otherwise means using a lot more code.]

Want to kill Return of the Jedimp?  John's warriors are very durable,
and I'm only scoring 45% wins against the latest :-).  When I get
this thing working I'll let you know.  It is NOT based on Harmony,
uses no magic numbers and has no core-clear.  It is a new way of
thinking about the spiral problem.

------------------------------

Things I haven't tried but may be worth investigating:
- "core clears" > 100% c may be possible using MOV >gate,>gate but can they
be made to do something useful, eg. mutate into a "normal" clear? 
- qscan -> pspace routine -> warrior may perform better against qscans.
- qscan -> non-booting warrior is also an option - one-shots are not as
effective as they once were. But make sure the main warrior is before the
qscan... if the warrior is a bomber it will also confuse one-shots.

Here is Damage Incorporated without qscan, just to make this issue less
empty :-) It's just Torch T18 with a d-clear.
