Abstract:  I will discuss some algorithms for simulating a flip of an unbiased coin by flipping a coin of unknown bias. We will discuss efficiency of several algorithms, where the expected number of flips is our measure of efficiency. We will also outline the proof of a conjecture by Hoeffding and Simons that there is no optimal algorithm.
