FOR REAL Non-cooperative Game Theory

Paul Manafort and Rick Gates are taken into federal custody. The feds found no evidence in the Manafort raid damning enough to convict either party or the Trumps of federal crimes.

The feds offer each party:

5 years in federal prison if they both confess and sell out the Trumps and the other party.

If either Manafort or Gates confesses and sells out the others, but the other party remains silent, the person who confesses walks free and the other party gets 10 years.

Neither party confesses, both are charged, and both spend 2 years in federal prison.

Manafort and Gates are interviewed separately and cannot collude.

What happens?

Why is cooperative game theory more mainstream/common/important than non-cooperative game theory?

(title should read "less" not "more")

Reading through Osborne & Rubinstein's game theory textbook, they seem to jump through hurdles to justify the inclusion of Part IV on cooperative games.

Why is non-cooperative games are more core / mainstream / fundamental? Do they have more empirical successes to point to, e.g. is there an auction theory counterpart which successfully applies cooperative theory?

PC + Xbox cross play game suggestions? Cooperative / sandbox / non BR- competitive`

Looking for ideas for some games I maybe am not aware of that are solid coop campaign, or coop experiences that cross play between xbox and PC. My friends and I already play a lot of warzone and such, but we are looking for some not-so-competitive more chill games or coop campaign type things.

We've played Sea of Thieves, Astroneer... things like that are sort of what we are after. I'd love a Farming Simulator cross compatibility but unfortunately that's not a thing. Stuff of that nature... things you can maybe have a couple beers while playing and still enjoy.

From a Game Theory perspective, how cooperative will Mitch McConnell will interact with Pelosi in regards to the next stimulus package given the current election status?

Just curious on what this sub thinks how likely Mitch McConnell will agree to each option:

  1. No stimulus package
  2. Smaller stimulus package $500B (original senate proposed)
  3. Medium stimulus package $1.8T (White House Mnuchin proposed)
  4. Large stimulus $2.4T+ package that Pelosi wants

Given that A. There is 2 senate runoff elections in Georgia to determine which side has control of the senate. This also decides if he is Majority or Minority senate leader.

B. A new federal budget also needs to be agreed upon by December 11 or government gets shut down.

C. The Fed Chair Powell calling for new stimulus package

D. Thanksgiving and Christmas is coming up. No stimulus package by this time would impact public opinion

E. Big corporate (Airlines), SMB and a lot of unemployed desperately need help.

Stakeholders

  • Pelosi and a democrats
  • Current White House, Trump
  • Incoming president Biden
  • Corporate interests
  • Public

What strategy will we most likely see?

Theory: GMErica is the name of the NFT Marketplace/Ecosystem/Metaverse. And what better way to change the perception of your business and re-brand from a "video game retailer" to "the Amazon of NFTs" by issuing a unique non-gaming NFT divided (Wu-Tang album) using your new NFT platform?

Title pretty much says it all. I remember seeing something from the last earnings report or somewhere on how GameStop now sees themselves as a "technology company", not just a retail store. We all know that, but the general public doesn't. I believe that GMErica will be the name of their NFT marketplace, and this will help change the optics and perception of the company. To prove that they are serious about expanding from just gaming and to showcase the capabilities of their new platform, they will issue the Wu-Tang album as an NFT dividend.

This will show people that they are looking to become the Amazon of NFT's, covering all different types of industries, not just gaming. I thought the NFT marketplace was going to be just for gaming myself initially, but then I realized I was thinking too small. They don't want to dominate the NFT gaming market, they want to dominate the NFT market, period. The NFT album dividend will essentially act as a proof of concept for their platform, showing how NFT's can be used in new and unique ways.

Again, this is just a theory. I have no way of proving any of this, it's just what makes the most sense to me.

How to incorporate cooperative culture into a non business entity?

This question may not make a ton of sense, so thank you for reading and considering.

Without giving too much away, I work in an institution of higher ed (public) and have been facilitating a campus composting program for several years now. The program is increasingly popular in the community but has some issues with sourcing sufficient labor. I have a hunch that we could experiment with a quasi-cooperative format (where labor is shared among the participants in the program), but we are not able to make a profit since we are working within a public institution.

Does anyone have any thoughts of how we could incorporate collectivism/cooperativism in a nonprofit setting? Is it possible to empower the β€œmembers” without clear financial incentives? Or is this just a bad idea? Thanks!

What are easy, non-violent, cooperative games for 3 local players?

I'm introducing my kids (6 and 8) to gaming with a regular gaming session where we tackle a game together. So far, we played through Kirby (a blast for them) and getting to where we can graduate from easy CPU enemies in Mario Kart.

As they are total noobs, their dexterity and reaction times just aren't there yet; they got too frustrated for New Super Mario Brothers. The cooking games seem way too hard/stressful.

I'd love to have something like the Lego games that we could play cooperatively together (I'd crush them if there was any kind of competition), but the Lego games are strictly two player games.

Any advice to get them into the hobby?

How to deal with a non-cooperative neighbor for their roof access?

We just bought an investment property and need access to our neighbor’s roof to paint a small section of our exterior wall. He asks for our contractors’ insurance, work. comp, etc. as well as the proposal for the work. Sounds reasonable. We provide them all, yet he keeps dragging. He asks for stuff like the part number of all scaffolding materials we plan to use. We are not going to place anything on his roof. We just need his roof access to attach/ remove a few triangular frames to our wall. He just seems to be non-cooperative. He won’t respond to my calls or texts either. This causes a lot of stress and delay for us.

For context, our other neighbor gave us permission to use his roof and yard after we agreed to his very reasonable terms that we would return them the same. The painting on that side was completed a while ago. He also complimented the work that we have done to the property. Such a nice guy!

How would you handle a scenario like this?

From Shapley Values to Explainable AI - An Accessible Introduction to Cooperative Game Theory and its applications

I gave a talk yesterday introducing Shapley Values and how they can be applied with modification to the problem of feature importance in Explainable AI. Shapley Values and SHAP are very useful for a wide range of fields and, as I mentioned at the end of the lecture, I think they provide tremendous value to scientists trying to explain models in order to explain the world, and to machine learning practitioners trying to explain models in order to understand/tune how they operate.

The talk expects a high school level understanding of functions and sets; everything else is introduced. The one exception is the mention of d-separation on a Bayesian Network in the context of contrasting interventional and conditional approaches; this is perhaps not essential, but still useful to understand.

The slides from the talk are available here (with a correction to the Glove Game example) and the my summary paper (without a proper introduction but with more examples and full citations) is available here.

Feel free to ask me any questions about the lecture, Shapley Values, or other state-of-the-art approaches to Explainable AI.

Cooperative Game Theory in Reinforcement Learning

Hey r/MLQuestions,

I've been working on a project which is based on multi-agent reinforcement learning. My professor tasked me with describing my approach through the lens of game theory. I've, unfortunately, never studied game theory, but now is a better time than ever, I suppose.

I've managed to pin down how I can frame my work as a cooperative game, but I have yet to understand why we'd do this in the first place. Specifically, I don't see the connection between game theory and optimization problems (which is how I view RL tasks). Through the papers I've been reading, I see how researchers setup a problem and deduce various game theoretic properties which, presumably, are nice, such as showing that the game has a non-empty core, but I don't understand what this means in the context of optimization.

Like, let's say I properly model my cooperative game so that I can show it has a non-empty core. This implies the grand coalition that is formed is stable, which means that, for my agents, they'll have no incentive to leave the grand coalition. I can appreciate, at a high level, what this means for my solution. But what does this give me, exactly? Does this suggest that my approach has some quality which is useful in terms of the optimization problem (such as some form of convergence)? Or is this weaker in that, for an optimization problem like this, a stable grand coalition is necessary for optimization to work (but doesn't guarantee the success of such a process)?

Mechanically, I think I'm grasping the notions of game theory enough to work with it in this context, but I feel I'm missing the overall point. In the papers I've read, it seems like they spend a fair amount of time proving these game theoretic qualities of their problem, then they move on to the optimization task and the game theory is never "used" again.

Can someone shed some light on this? I'm really just looking for more intuitive explanations as to how game theory can be applied in this setting, but any advice or recommendations would be appreciated. If it helps, one of the main papers I'm referring to is here, but I wouldn't get hung up on the details of this particular paper since it only resembles my work loosely. Also, if anyone can suggest a better place to ask this question, I'd appreciate it to. Thanks!

What would be your ideas for a campaign mode for a non-cooperative game ?

Hi guys !

Useless context

I have a neat little game where Greek Mythology heroes race each other in a sort of dungeon to find medals and be the one to escape (with a freaking Minotaur chasing them). The game has been tested dozens of time by its author and it works well. The main art is being made. We're getting ready for Kickstarter in February while we'll attend Cannes's Festival with DΓ©bΓ’cle's team.

Why a campaign

As a player, if i have 4-10 "missions" to do, I'm more inclined to put this game as a priority instead of shelving it. And a campaign, with maybe content to unlock with soft legacy (Γ  la Zombie Kids)

I'd like to add a little extra layer to the game, by adding a bit of campaign elements to it as bonuses to the campaign. I know, people want legacy games and campaigns everywhere since Pandemic Legacy. But I really love this game, and I feel there's a great concept hiding behind all this confusion i'm facing right now.

The state of the "campaign"

We've been brainstorming a lot to find ideas to implement this as it's not a cooperative game at all. Right now my idea is that the players have to face different challenges (each challenge being the dungeon with different rules / parameters) in order to ... I don't know.

The main issue is players are not cooperating. And I can't guarantee the players will be the same from one game to another.

Maybe it's not a campaign, but a tournament, or challenges by the gods. Maybe it's a time loop where every iteration the game changes until... until I don't know yet but I like the idea.
