Robot Prisoner's Dilemma - Mccoyn Wins - Round 2 in Limbo

[JDodge]

Seriously though, my robot will be named (non-derivatively) Tobanikom.

Nobody will get this joke.

[Albert B. Rampage]

Still open for registration ?

[Sudo_Nym]

Damn, now my name sounds dull. It it too late to change my robot's name to "Hammer of Mokina"?

[Mokina]

Damn, now my name sounds dull. It it too late to change my robot's name to "Hammer of Mokina"?

Ugh...

I might as well call mine CoolBot or something just to avoid copyright issues.

Oh, wait...

[Khelvaster]

When does this start?

[mccoyn]

Thats a good name. My robot will be named CoolBot 8)

[Mokina]

*Changes the name back to Mokinabot and sues impostors*

[JDodge]

Tobanikom is not an impostor. It's a doppelganger.

[Mokina]

Yeah... a

backwards

one! Your sly treachery does not escape me!

[Occult]

Mokina quit your complaining.

[Fritzler]

/in

my robot is named

Rom, the greatest of the space knights

[Pie_is_good]

Things will be resolved tomorrow night; any robots not submitted by then will not participate.

[Guardian]

/in if not too late.

My Robot's name is

Empath

.

[Mokina]

Is it empathetic?

[PookyTheMagicalBear]

/in My Robot's Name is "The Crimson King"

[Samruc]

/in, unless too late. My bot is, of course, SamBot

[Pie_is_good]

The Competitors!

If you actually expected me to dig through the thread to find your Robot Name, you get laughed at. People who included it in their PM have been duly cited.

IF it's the last round choose "foe." Always.

ELSEIF it is past the 3rd round and the opponent has never yet chosen "friend", consider them an eternal foe.

ELSEIF it is past the 3rd round and the opponent shows an alternating pattern starting with "Friend," always defect.

ELSEIF it is past the 3rd round and the opponent shows an alternating pattern starting with "Foe," always defect.

ELSE choose "friend"

* FIRST ROUND: ALWAYS FRIEND

* AFTER FIRST ROUND:

--> IF OPPONENT'S PREVIOUS CHOICE WAS FRIEND, THEN CHOOSE FRIEND

--> IF OPPONENT'S PREVIOUS CHOICE WAS FOE, THEN CHOOSE FOE

* LAST ROUND: ALWAYS FOE

Foe all 10 times.

My robot will always choose Foe.

Choose foe unless the last three inputs from my opponent were friend.

Rounds 1 and 2, I defect. For rounds after 3, I do what my opponent did the last round.

Going foe all the way.

1: Defect
2: Store a value of 0 for X
3: If Opponent defects, subtract 1 from X
4: If Opponent cooperates, add 1 to X
5: If X>0, cooperate
6: If X<0, defect
7: If X=0, return to line 1
8: Return to line 3

Round 1: Always friend
Round 2-6: If both players picked friend last round choose friend again. Otherwise, choose foe.
Round 7-10: Always foe

so, foe 24/7

Each round, start out with Friend.
Then, until the last choice, do whatever the opponent did last round.

Then, the last choice, defect.

choose 'foe', unless opponent has chosen 'friend' for both of the last two rounds.

Cooperate,
then Choose the same thing the other person chose last time.
Then on the Last one defect

Start with friend

Continue with friend if opponent chose friend the last turn

If at any point opponent chooses foe, proceed with foe all the way until the 9th time, then my robot will choose friend, then foe the turn right after.

Always choose foe on the 10th

...stay tuned; results posted shortly!

Congratulations to Mccoyn, and to Sudo_nym and Samruc as runners up!

[Samruc]

Yay! But of course I should have gone 'always foe' on the last round too.

[Pie_is_good]

Oh man. This game is a BITCH to resolve. 14x14x10 games to figure out and calculate... ugh.

Anyways, I was happy to see the All-Foe bots lose; more than one person claimed that they had broken the game by submitting that bot.

Samruc and Sudonym had practically the same bot, which played quite interestingly - it was very, very cautious; it never lost points, but if the opponent trusted it for long enough, it scored big. Nice design, but both could have been improved by a "Always Foe on the last round" clause.

Mccoyn's bot was a very nice idea. It accepted the minimal losses from the All-Foe designs in exchange for repeated, large scoring against the trusting bots. Then, it played the inevitable backstab at six - cashing out on the extra points before the opponent defects anyways for the tenth round. Another important point of this bot was a subtle difference in wording - the bot only cooperated if

both

players chose friend on the previous round. This allowed the bot to sidestep pitfalls that Blackberry, Guardian, and Pooky fell into against Xyzzy's bot - In the setups, the two would alternate between Foe/Friend and Friend/Foe such that they would both lose a significant amount of point. With Mccoyn's bot, though, that didn't happen - the cycle would be cut off once Mccoyn dinged xyzzy for two of the points back.

For the next round, I guess I'll mod it again. Any suggestions for changes in point value, now that we've had a game under our belt? Any requests for rules mutations? Let me know.

Pie

[Samruc]

Glad you want to mod it again, Pie. I suggest we limit the number of bots in each round to maybe eight or ten, to keep it on a reasonable amount of games.

I thought this was great fun. You might want to reduce the penalty of -3 to -2, to get some friendlier bots (or would the symmetry be a problem?). Besides, I probably would change the rules for the last round, to be +2/

-0

for backstabbing, otherwise the scoring seems just fine.

I'm up for a new round, whatever the rules.

[Xdaamno]

If you do a new round, definatly /in. I'd probably keep -3 as -3.

[Brutal Assassin]

Yeah, I was going to change my bot to exactly what McCoyn had the day before but I was curious how the "All foe" bot would resolve. Thing is, if more bots had opted to program randomly, or with a set pattern, then McCoyns idea would have been shot to hell. But with everyone doing either "Always" or "If then, Always" it worked out perfectly for him.

[mccoyn]

I hadn't even considered an all-foe opponent. Basically, I thought friendlies would be popular so I started out friendly. To minimize damage from people trying to manipulate my program I lock on to defect if I'm back-stabbed just once. And of course, with two friendlies whoever back-stabs first wins! I would have lost if there were too many friendly bots that waited longer to back-stab.

I could mod some games. I think it would be easy to write a program to run the games. I'll let Pie run this round though so that everyone gets a chance at taking me out.
