Greedy actions

WebGoing through more or less all recent publications I always find the use of epsilon greedy as the action selection strategy. On the other hand Sutton (as far as I remember) suggested as early as in the 90's that softmax is superior to epsilon greedy in many cases, since it is more efficient in exploring therefore learning faster.
