Greetings.

Welcome to the 22nd issue of Core Warrior.  We've had a flurry of activity
this week.  Over half the warriors on the '94 hill are brand spanking new.
The past three weeks have brought significant change to hill as long standing
veterans have been falling to young upstart pspacers.  Enjoy the show.

Weekly age: 128
New warriors 13  Turnover/age rate 10%
Average age: 350 ( 333 last week, 431 the week before )
Average score: 142 ( 140 last week, 142 the week before )
The top 25 warriors are represented by 12 authors.

Boeren is on top once again this issue and has been for most of the week.
Only in 6 challenges has another warrior claimed the top spot--Thermite II
three times, Hipshot v2.1 once, and Naked Dancer twice.  Grilled Octopus
reminds me of quiz's long dominance at the top.  Except for the fact the
Grilled receives periodic updates.

The past three weeks have purged some of the ancient warriors from the hill.
This week Hazy Shade of Winter was _killed_ by JKW at an age of 616.  Marsden
lost Blizzard at an age of 713.  Both will enjoy rankings in the corewar Hall
of Fame however.  Four warriors are over 1000 now--Impfinity, Frontwards,
Evol Cap, and Thermite II.

We've seen 14 versions of Naked Dancer this week.  Perhaps Bezzi will be
satisfied with the number two spot.  Gem of the Ocean has also been through
several mutations.  Will these guys ever be content with anything less than
the number one ranking? 8)

Bombers are the dominating strategy at the moment.  At least seven of the top
ten warriors are bombers or have bombing components.  Last week, 130 points
would have gained the hill.  Not this week.  135 points just for 25th place.

Ian Oversby has made a fairly quick jump to the '94 draft hill.  Sloth v0.4
is his highest ranking warrior at eleventh place.

Only eight warriors declare using pspace in their strategy lines.  And the
qscanners don't look all that effective this week.

Hazy Shade of Winter enters the hill knocking off Boombastic by Maurizio
Vittuari.  Blizzard stops climbing settling at 17th place.  Remember when it
only took an age of 350 to make the hall?

Barrage and Chameleon should both make the hall next week if they survive.

How unfair to inflict Jack in the box on the beginners hill!  The '94 draft
hill had to tolerate him for a _long_ time. 8)

basehead was briefly seen on the '94 hill.  Although his warrior scored well,
it was killed by the author.  Hmmmmmm.  Interesting strategy.

Is anyone on the b-hill in favor of increasing the age limit?

The Hint

Before the '94 draft language, jmz scanners could only find non-zero 'b'
operands.  Having zero value b-fields in your warrior was a definite
advantage.  But with the new draft, many more options became available.
Scanning instructions can now scan .a .b .ab .ba .x and .i.  Few authors
bother with zero operand fields anymore, so scanning .b may be just as
effective as scanning .i when searching for enemy code.  Consider this:
TimeScape style replicators contain no zero b-fields (except in the launching
code).  Wild Card scores 175 against it scanning .i, 173 scanning .b.  Of
course TimeScape copies have tons of zero a fields.  Scanning .a scores a
miserable 131.  Irongate has one zero a-field and one zero b-field.  Scanning
.a and .b score around 132 points.  Scanning .i scores 145 points.  Definite
problem.  However, this technique works best against classic stones.  A stone
usually will dec/inc the a or b field thus distracting scanners.  By only
scanning .a or .b, you have a chance of not finding any dec/inc locations.
Juliet storm modifies a-fields.  With a mov #2667, *0 imp added to it, Wild
Card scores 118.5 points when scanning .b versus 108.5 points scanning .i.

Submitting my scanner against the hill with different options had significant
effects on the individual scores of some programs.  Drastic enough I don't
want to mention names.  But the overall score against the hill tends to
balance out.  However, if you're having a real problem with a few particular
programs, changing your scanning criteria just may be the key.
