Quite an intresting mathematical experiment: Even the infamous prisoner’s dilemma changes to favour co-operation when groups enter the equation!

Game Changers: Stories of the Revolutionary Minds behind Game Theory

In this lively history of game theory, a gifted math educator and science writer explains for lay readers the uses and value of this innovative yet easy-to-understand approach to mathematical modeling. Essentially, game theory interprets life as a game with mathematical rules. By following the rules, decisions can be calculated that result in the greatest benefit for all participants.

Update - I swapped out the table of results for a difference chart. Now it shows who had the biggest advantage over the course of the simulation.

There's now a 'Random' player, which will be useful for testing strategies against 'just being lucky'. Also happens to give me some more interesting graphs to view.

I plan to add more results views, as well as new options for tweaking the simulation settings. Then I'll focus on custom strategy building.

Just started a new side project this month (year?)

It lets you test out different strategies against the Prisoner's Dilemma. The idea is you can see performance over several rounds, and tweak things like number of rounds, whether to hide context from players, etc.

Eventually, I will enable the user to create a strategy and build a leaderboard. I'm not there yet, but I want to use this as an opportunity to try out some techniques.

I have now been waiting twenty minutes for something that should have happened in ten minutes. Do I leave and come back via a detour another day to collect it, or hope that I get it in less time than the detour? I feel like a game theory exam question.

Why don't the world leaders seem to take the more seriously?

Daily, more and more regular people are realizing that our "window" to gradually transition away from |s closed, long ago, and that we must stop burning them NOW, must stop sucking them out of the ground NOW.

And yet, our leaders—including many quite progressive ones—keep right on planning this slow-motion, decades-long, someday-switch.

Why?

IDK actually know ... I'm just another regular person, watching it unfold.

Quitting right now would, in fact, be bad for the global economy. Just think, eg, of all the people still paying off loans on their ICE-cars, who wake up tomorrow to find that gasoline is no longer available at any price, and their cars are now less than worthless? And a thousand similar wrenching changes to people and businesses.

But that's actually the best-case, if the whole world quits together.

What if just Germany quits, unilaterally? Or Canada? Or even the US?

Then that country's economy crashes alone, and the rest of the world reaps a benefit, because fossil fuel prices would actually go down, thanks to the decrease in demand.

Every leader on Earth has been aware of this conundrum, one way or another, for 40+ years. Every leader keeps waiting for someone else to take the plunge first.

And we lemmings march on.

Here's a fun little game on game theory that my teacher found. It is about how various strategies fare in a multi-round game of Prisoner's Dilemma, and how it relates to why society sucks now.

Help! How can an autonomous p2p network set the price for storing data? (safenetforum.org)

Your ideas needed... Pricing seems a simple problem, at least if a human can be in the loop but how can a massive network of simple nodes (think ants) come up with pricing based on a handful of those nodes and not let crafty humans or AIs game the system?

This is a fantastic, quick little game-slash-educational tool that teaches you about game theory and trust (and tests your knowledge of it). Highly recommend giving it a go! https://ncase.me/trust/

It’s in your browser, and you don’t need to be a gamer to enjoy this. Also great for kids, I reckon.

question for everyone...

Is there a name for when an optimal strategy is avoided because the optimal strategy is easily defended against when you know the person is using it in the first place?

Or the reverse, where someone might intentionally use a very poor strategy specifically because the user would never expect a user to pick a poor strategy and thus, at least when assumed it wont be used, becomes a strong strategy?

They’re still trying to ban

https://doctorow.medium.com/theyre-still-trying-to-ban-cryptography-33aa668dc602

Call this the “enforcement nexus” — for a government to enforce a law, it needs something to seize. Governments have broad latitude to seize things and people within their territorial borders (though this is not absolute, as I’ll discuss below). But when it comes to conduct outside a government’s territory, enforcement depends upon the cooperation of another government — this is why so many crime dramas turn on a desperate dash for countries that don’t have extradition treaties. Governments can project enforcement power into any territory that will allow it to seize the people or property of its adversaries. When the Argentinian government defaulted on its bonds, it failed to reckon with the fact that its US dollar holdings were stashed in the US Federal Reserve Bank in New York. That meant that the vulture capitalists seeking to squeeze Argentina could argue their case in their home court in the USA, seeking a judgment that could be enforced domestically — that is, by seizing the Argentinian government’s assets held on US soil.
National firewalls are everywhere today. Sometimes, they’re sold as turnkey solutions — by both Chinese and western firms — to poor countries with very little technical capacity of their own. Spy agencies from large, powerful countries love it when poor countries install foreign-made national firewalls, as these are key to “third-party collection” (when a spy agency taps into another spy agency’s files) and “fourth-party collection” (when a spy agency taps into another spy agency that has tapped into another spy-agency’s files). As national firewalls proliferate, so too do enforcement nexuses. After Edward Snowden revealed that US tech giants were allowing US spy agencies to plunder their user data, the EU imposed a (perfectly reasonable) data localization regulation that required US tech companies to keep Europeans’ data on servers within the EU (this regulation remains contentious and fragile). The EU doesn’t have a regional or national firewall, so tech giants who don’t want to comply with the regulation could simply withdraw their sales offices and engineering departments and lobbyists from the EU and ignore the rule — at least to the extent that they could convince US courts not to enforce EU judgments against them. But the EU has other enforcement nexuses it could rely upon. It could order European banks and payment processors to block payments to tech firms that ignore the localization rule. Payment processing remains a
Enter American culture-war nonsense. In Texas, they want to ban websites that explain how to get an abortion, as well as sites that ship the pills for a medication abortion. In Florida, they want to force bloggers who write about the state government to pay a fee and register with the state, prohibiting anonymous commentary about the state legislature and its actions. Florida has also required that online providers cease permitting their users to display pronouns other than the ones they were assigned at birth. Of course, online services have no way to know what pronouns any of their users were assigned at birth, so sites like Github are complying with Florida law by simply not displaying pronouns to Floridian users. The biggest barrier to enforcing these laws is the US Constitution, which these laws assuredly violate. It’s entirely possible that a lower court will uphold these laws. It’s conceivable that an appeals court will do so as well. It’s not outside the realm of possibility that the current Supreme Court — illegitimately stacked with far-right partisan hacks lacking any shred of principle — will follow suit. But it’s far from a sure thing. It’s not even clear whether the legislatures that passed these laws and the governors who signed them want them to be enforced. After all, if these policies do come into force, large numbers of corporations are likely to shutter their offices and move out of state (especially in Florida, an increas
