What is q-table?
Q-table: A table with one row per situation and one column per action, storing the current estimate of the action-value for each pair. It works only when the numbers of situations and actions are small enough to list, such as in small grid worlds.
Q-table: an example
A 5x5 grid with 4 moves needs a 25 x 4 table, holding 100 numbers, all starting at 0.
