Non-Neural Network algorithms for large state space in zero sum games

I was reading online that tic-tac-toe has a state space of $3^9 = 19,683$. From my basic understanding, this sounds too large to use tabular Q-learning, as the Q table would be huge. Is this correct? ...

How does the Markov assumption hold true for episodic task?

The Markov assumption assumes that the current state is sufficient for taking the next action. Consider an episodic task, where the RL agent is trying to learn to play the game of tic-tac-toe. Here, ...
