cepheus

A perfect strategy like Cepheus will gradually take all your money unless you also have a perfect strategy.

After all, Cepheus honed its strategy by playing the equivalent of a near-perfect opponent that made practically no mistakes.

Any chance of the code being released or a cepheus style answer key being provided?

There are almost certainly other approximately perfect strategies, which would break even against Cepheus over the long term, but you can't beat it.

If this ends up killing Cepheus I will have wasted thousands of hours of my time.

>After all, Cepheus honed its strategy by playing the equivalent of a near-perfect opponent that made practically no mistakes.

For example if Cepheus gets an 8 and a 3 and you open with a bet, it will call your bet if they're the same suit, otherwise it will fold.

You can examine the Cepheus strategy for yourself, if you could memorize it (it's too complicated) and were capable of making truly random decisions (Poker is a game of chance and so your strategy needs random action) you could reproduce it and be exactly as good at the game as Cepheus is.

I'm aware of Cepheus (essentially a solution for perfect Limits Heads Up) and I see they did some further work in No Limit, but there isn't anything since a February 2018 publication.

In principle if you could memorise Cepheus you could play the same strategy, but it's basically a vast number of fractions/ percentages so you're not going to -- and it's important to note that while the strategy is unbeatable it is not the best way to extract money from weaker players.

Yes, if it's very chip poor, Cepheus could run out of chips before it stops being unlucky and takes your money, but that's unavoidably true anyway in Poker due to it being a game of chance as well as skill.

> While there is no reason to not believe them let's see how they fare vs other near optimal AIs They mentioned that: Burch warned that human poker players should take the Cepheus strategy with a grain of salt.

Cepheus is actually a good Rorschach test for players who say "GTO" a lot.

Cepheus doesn't care about "stack depth".

It's important to understand that Cepheus isn't AI, it's an (asymptotically close to) optimal strategy for Limit Heads Up ("Limit" means you don't need to choose bet sizes, they are fixed, which makes the problem much simpler), and since poker is a game of probabilities the strategy is probabilistic too.

If you actually grasp what game theory optimality is about, you see Cepheus and you're like "OK, I'm done playing Heads Up Limit" (and indeed although it was once somewhat common you won't find any professionals playing this for some years now).

They compete in Alberta yearly championship every year so it will be easy to see how it goes for Cepheus.

The former would cause you to publish (like Cepheus) the latter not so much.

Unlike Cepheus, Pluribus doesn't have an incredibly boring yet precise strategy mapped out that you could copy, it's a result of AI learning.
