Deadline: Saturday, November 12, 2005, 9pm CET

The Rules

Ok, after a quite hard second round I decided to make it a bit smoother using a well known parameter set. This time it's under the 94nop hill rule except the max. warrior length is just 50. P-space is allowed this time, but you have to share the same p-space than your opponent using PIN 13. To force you for agressive strategies the scoring scheme will be Win: 1 Point; Tie: 0 Points, Lose: 0 Points.

The parameter setting are:

max. Cycles80000
max. Processes8000
max. Warrior Length50
min. Distance50
p-spaceallowed, but must share the same PIN 13

The commands for pmars is:

pmars -s 8000 -c 80000 -p 8000 -l 50 -d 50 -r 1000 -= "(W-1)/S"

Fixtures and Results

Well, I can't put you off the scent because you all see through the scoring scheme;-) I thought I would see more p-spacer, but it looks that the max. warrior length of 50 wasn't enough for you to consider it.

el kauka vs. Roy van Rijn

Fizmo's Comment

Roy seems the clear favourite in this match. Let's see if el kauka can surprise him with an unexpected entry

The Comments

el kauka:
Regardless what i'm sending - to face roy means you
are doomed. Victory needs no explanation, defeat allows none
The Results

Roy sent a modified Hullabaloo, while el kauka sent a p-warrior including a oneshot. That sounds like a close battle, but the p-warrior's oneshot wasn't able to dominate over the stone/paper. Overall, a clear victory for Roy van Rijn.

S.Fernandes vs. inversed

Fizmo's Comment

A very interesting match, because both surprises with very good entries so far.

The Comments

This time I'm not well prepared, I just had no time. And the rules are
too typical (still can't understand why Fizmo alternated scoring formula, 
this doesn't affects 1-on-1 results).
So I took my best warrior PhatPaper, added a stone, trimmed qscan
and here it is; no time to optimize it. It only loses to some oneshots.
I've tried to make a P-switcher, but it exceeded maxsize by few instructions.
Probably I'll lose out but anyway participating in CSEC was a great fun.
The Results

inversed sent a qscan into stone/paper, while Fernandes paper/imps. The slight advantage of inversed's qscan seems lost by the slower booting of his stone/paper. The match was running nearly in a tie but S. Fernandes' entry finally achieved some few wins more.

John Metcalf vs. Chip Wendell

Fizmo's Comment

Two corewar giants clashes in this match, but only one can survive. Who will it be?

The Comments

Chip Wendell:
1. First off: use p-space, or not? The short warrior length 
would make it difficult, plus I don't have much experience 
building p-warriors. So I won't use it, but I may brainwash 
if it doesn't hurt me too badly.

2. The "aggressive" scoring scheme would be a factor to 
consider if this was a round robin, but for a one-on-one 
battle, it's completely irrelevant. As with the usual scoring 
formula, the only important thing is to win more than I lose, 
regardless of ties.

3. So, what strategy should I pick? Stone/papers seem to be 
the most robust warriors, vulnerable mostly to scanners. John 
is a scanner guy, but he may avoid those for that reason. 
Besides, there's a chance (however slim) that John will be 
fooled by the scoring scheme into thinking that I won't enter 
a paper.

4. Hullabaloo seems to be about the best recent S/P, so I'll 
start with that. The qscan section is too long, but I don't 
want to enter without one, since that would make me even 
more vulnerable to scanners (no decoy). Reepicheep has a 
nice short one, so I'll borrow that. It fits very nicely.

5. I want to add brainwashing, to foil any of John's attempts 
at p-brains. After wasting time determining that adding an 
STP line to the paper wrecks the paper, I added a line to 
the stone. It drops from .5c to .4c, but it doesn't seem to 
hurt its score much, so it's probably worth it.

6. Send it in, and cross fingers...
The Results

John sent a anti-imp stone hoping for a scanner or stone/imps, while Chip expected a scanner or a p-spacer choosing a stone/paper with brainwash. Finally it was a clear victory for Chip Wendell.

German Labarga vs. Zul Nadzri

Fizmo's Comment

Zul Nadzri sent the last rounds always papers, will he continue? Will German Labarga surpises Zul with something unexpected?

The Comments

German Labarga:
  Zul will surely submit a p-spacer with some kind of brainwashig.
If i submit a single warrior it will be probably beaten by
any of his components, so i have to submit a p^3 with some
brainwash detection cappability.

I first wanted to use a scanner+stone/paper or similar using a version
of Gihegruoerg, ;but can't fit something like that in 50 instructions.

So finally try a p-spaced paper/imp, with and without stone.
I know that there will be many ties and the scores will be low,
but taking a few poitns from my opponent would be enough to win.
The p/i is very strong and i think it can only be beaten by a
fast anti-imp scanner, so then, the stone pops up.
Zul Nadzri:
Again (and again) victory mostly depends on good anticipation 
of opponent's strategy. Usually, it is better not to anticipate 
anything and put the passion into a warrior. This time, I am going to 
resurrect another off-hill warrior. May be can submit to the hill after 
this, after all the effort spent for this round.
I picked Dawn 2, Roy's warrior because the core is definitely less than 
50 lines.
Why Dawn? I admit it has disadvantages. So do other warriors. Remember 
the stone/scissor/paper analogy?
Why paper? I am sure G.Labarga loves to destroy papers with his scanner...
...and I am going to give him a challenge that he is looking for! You 
better win dude!!
More tips: this warrior can't beat Recon2
First, I removed Dawn's Qscan to meet the 50 lines standard.
Second, I removed all empty codes, making the warrior compact to attract 
scanners to the 'decoy'.
Third, I filled gaps with stp.ab >0, #0 just in case it can be executed. 
Put PIN 13 on top.
Fourth, Gave a good name "Peaceful Jawn". Ain't is beautiful?
Fifth, Jawn = John + Dawn. Acousticly, 'Jawn' is 'John'...almost the same 
sound and frequency.
Sixth, send early to Fizmo and enjoy my holiday.
Seventh, if your name is John, this is not related to you ;)
The Results

Zul didn't sent a p-warrior as German expected but paper/imps. There was no scanner who could be defeated by Labarga's p-warrior to get some wins. Zul get a close victory with only a few (early round) wins because he hadn't spent cycles for a p-switcher before launching his code.

The Second Chance Tournament Tree Fixtures

There is a second chance for all players who wants to continue the CSEC2005:

Here are the fixtures for the second round:

datagram vs. LAchi

The Comments

I don't know who my opponent is, but assuming they don't make 
a scanner that is better than my scanner, I should have pretty good 
chances to win. The warrior is a p-switcher that is 2 parts zooom 
scanner and 1 part kline paper. The scanner uses a SJD clear,
SPL-JMP-DAT; works better against imps than SSD.  Kline paper does 
well against most Stone/Imp. Should be immune to brainwashing. Not 
optimized, but scores decently against most mid-level warriors.

The Comments

Michal Janeczek:
The new scoring scheme doesn't change anything in 'one must 
fall' tournament.. So given my lack of time and decent performance 
of Microvenator in RF4, I'll submit just this. Hopefully the 
new name will be enough to stop Jens :)
