k-means clustering for poker hands based on earth mover's distance (EMD)

An implementation of hand abstraction algorithm for two-player nolimit Texas Hold’em poker introduced in Potential-Aware Imperfect-Recall Abstraction with Earth Mover’s Distance in Imperfect-Information Games.

• g++ ( >=7.4 )
• make
• cmake (Just for building googletest)

Please don't forget to run git submodule update --init --recursive after checking out. Then run the clustering program as follows:

make
bin/poker-hand-clustering

In data folder, turn_kmeans.csv and flop_kmeans.csv will be generated. Here we represent cluster by hand indexes implemented in kdub0/hand-isomorphism. Thanks.

This is a rewrite of my old-fashioned code to release, but whether this program works is not yet confirmed enough because of its requirement of computational resource etc. In the future, I will add more tests and run this program with enough computational resource to confirm it.
