'Game Theory' on Coursera (Jan 7 - Feb 25) (2 Viewers)

Yeah definitely, but it is essentially the same as a Prisoner's dilemma. I can see how being a friend could change the outcome, but how would repetition change it?

I haven't done much of this before so may be way off base but I think that trust is an important issue in the long-term version. Making choices to steal most or all of the time will lead to a rational opponent moving to stealing most of the time regardless of his initial intentions. If you prove yourself to be trustworthy, a pattern of mutually beneficial outcomes can occur. (As opposed to an opponent shutting down on you and going for steals the entirety of the time, in which case you will not make any money through this game).

I think I'll have a go at the problem set tonight.

Might consider financial economics, there's no compulsory macroeconomics units later on... Thanks for your help OzKo!

When treating it as a one-off game with a stranger at least. If played repetitively or with a friend etc I think it is a little less clear cut.

The best known general strategy over multiple iterations of Prisoner's dilemma (and I assume for this game as well) is called tit-for-tat. In the first round you play 'nice' i.e. cooperatively, and in every subsequent round, you do whatever the opponent did to you the last round.

How they came across this strategy is a cool story. There was a prisoner's dilemma contest where contestants had to write bots that played prisoner's dilemma against other contestants' bots. Many contestants submitted highly intricate and complex artificial intelligence programs that configured their playing parameters based on the opponent's playing style etc. After pitting all the bots together, the winner was the tit-for-tat bot, which comprised of 4 lines of code.

Yeah, I figured that some 'nice' strategy which still punished greedy behaviour by opponents would be best.

No worries.

Best of luck!

seanieg did you do many eco units during undergrad?

None, wasn't particularly interested in economics and there were a lot of other courses I was more keen on. Game theory itself has always interested me in a way though.

 

[OzKo]

Ended up getting 6/9 for the first problem set.

I don't know about you guys, but these 'online courses' never seem to work for me.

In what sense?

 

[RookieLaw]

Really enjoying this, only had a week to learn about Game Theory at uni

 

[Verify]

In what sense?

In the sense that the whole course is online, therefore I seem to have an attitude where I cannot take it seriously. But don't get me wrong, I find these courses extremely helpful, just that I can't maintain the same amount of motivation as the course goes on. Any tips? :S

Maybe take notes while you do the course?

can someone let me know if im doing this correctly

If anyone is at USYD, take ECOS2901 and ECOS3901 which are effectively game theory courses. Both courses have fantastic lecturers too.

 

[Trebla]

Hmm...I don't see Arrow's Impossibility Theorem on there. That was like the most mind blowing theorem I encountered when I learnt game theory.

 

[OzKo]

Content for Week 2 is now up.

 

[Nooblet94]

How'd you blokes go in the problem set? I got 7.5 the first time but only 5.5 on my second and third attempts :/

(For week 1, that is)
