Drawing on one of the great opera librettos based on medieval sources, Wagner's Tannh{\"a}user, we shall illustrate the use of optimal randomization strategies that can be derived by applying notions of dominance or trembling-hand perfection. Particular attention is paid to the employed randomization device.}, url = {http://else.econ.ucl.ac.uk/newweb/papers.php#2006}, author = {Harmgart, H. and Huck, S. and Muller, W.} }
