Class Documentation

class Connect2 : public bitrl::envs::EnvBase<TimeStep<std::vector<uint_t>>, DiscreteVectorStateDiscreteActionEnv<53, 0, 4, uint_t>>

Implementation of Connect2 environment from https://github.com/JoshVarty/AlphaZeroSimple Initially the environment has all its positions set to zero. When a player makes a move then the position corresponding to this move.
