Black Widow

This one took me by surprise. I revamped my old Scorpion scanner, added a
qscan optimized by Steve Gunnell and fine tuned the boot distance against
every oneshot available.

Here's the exact version from the 88 hill:

;redcode

;strategy qscan -> scanner
;assert CORESIZE == 8000

QGAP equ 1168

qfirst equ (qp2+2*qstep)

qstep equ (QGAP+QGAP)

qi equ 5

end qscan

And here's the hill results:

Replicant

This one is based on ROUS which always struggled with standard processes. I
was playing with alternative replicating bombing loops and stumbled upon one
that's pretty effective.

Here's the exact version from the 88 hill:

;redcode
;name Replicant
;author S.Fernandes
;strategy paper
;assert CORESIZE == 8000

pstep equ 2198
ipos equ 1681
spos equ 3657

paper mov #26 , 9
loop mov <paper , <pboot
mov <ipos , <spos
add loop+1 , @loop+3
mov bomb , <loop+1
jmn loop , paper
spl @paper , <-2667
pboot jmz @0 , pstep
bomb dat <2667 , <5335

end loop

Here's an alternative loop that didn't perform as well:

;redcode
;name Replicant--
;author S.Fernandes
;strategy paper
;assert CORESIZE == 8000

pstep equ 2189
sstep equ 1532

paper mov #17 , 9
loop mov <paper , <pboot
mov bomb , @2+sstep
add #sstep , @loop+3
mov bomb , @loop+1
jmn loop , paper
spl @paper , <-2667
pboot jmz @0 , pstep
bomb dat <2667 , <5334

end loop

And here's the hill results:
