chooseAction method

int chooseAction(
  1. int state
)

Choose an action for state using epsilon-greedy. Ties are broken by first occurrence (stable determinism under a seed).

Implementation

int chooseAction(int state) {
  if (state < 0 || state >= nStates) {
    throw RangeError.index(state, List.filled(nStates, 0), 'state');
  }
  if (_rand.nextDouble() < epsilon) return _rand.nextInt(nActions);
  return bestAction(state);
}
