WebFurthermore, when using the Boltzmann softmax operator in the Expected Sarsa update, for the expectation of the value in the next state, this operation is not guaranteed to be a non-expansion (Littman, 1996; Littman & Szepesvári, 1996). As mentioned earlier, mellowmax operator was designed to fix this non-expansion issue (Asadi & Littman, 2024),
