States are indexed using the first dimension, however, the entries for a given state are compacted and stored in adjacent index, value pairs which are searched for rather than accessed directly (see get_action()). The actions stored in the table will be either shifts, reduces, or errors. Shifts are encoded as positive values (one greater than the state shifted to).
