Does OpenSpiel support Pursuit-Evasion and HUNL Subgames

[menglinjian]

Hi,

I'm currently working on a new algorithm for solving EFGs and would like to test it on some specific games. Does OpenSpiel support:

1. Pursuit-Evasion games?
2. HUNL (Heads-Up No-Limit) poker subgames?

It would be great if anyone could confirm or point me to any relevant resources/examples.

Thanks!

Unfortunately OpenSpiel does not have any pursuit-evasion games in the suite. Which ones did you have in mind? Are there any standard ones from the literature that would be good to adopt? We can maybe add it to our wish list.

HUNL subgames, I believe, should be possible from the universal_poker but I'm not entirely sure how. I'll tag a few experts to help clarify that.

Ok there are some HUNL subgames in this file:

open_spiel/open_spiel/games/universal_poker/universal_poker_test.cc

Line 839 in f68f2a3

void TestSubgameCreation() {

I believe @michalsustr added them originally. @Drazcmd recently did some bug fixing and maintenance work in this game, he may also know. Going to tag @jhtschultz and @VitamintK as well, and see also this Atan03 from this thread who had a similar question: #1168)

Thank you very much for your response. I have already contacted the person you mentioned via email.

Unfortunately I'm not super familiar with how fleshed out the subgame functionality is, my changes were all in unrelated sections of the code.
That said, +1 on open_spiel/games/universal_poker/universal_poker.cc and universal_poker.h probably being the right places to look - e.g. doing a quick search for the string 'subgame' in those files I see a lot of promising matches
