Implementation of CFR and MCCFR (outcome-sampling) with rust.
-
The expected payoff for the first player shall be -1/18
-
Probability of betting with hand card 3 is 3x of with card 1
-
Always pass with hand card 2
Here's the example output for 100000 iterations.

Explore with epsilon=0.06. Average payoff = -0.05138
| History | Check Probability | Bet Probability |
|---|---|---|
| 1 | 0.805 | 0.195 |
| 1C | 0.68 | 0.32 |
| 1B | 0.97 | 0.03 |

| 3C | 0.03 | 0.97 |
| 3B | 0.03 | 0.97 |
| 3CB | 0.03 | 0.97 |
We get 0.03 here because we choose epsilon = 0.06 and we have 2 actions to choose from.
