Center node: "uncomputability of the generalized capacity"
  Abstract: What is the maximum rate at which we can send information over a channel? We define the capacity of a channel as the answer to this question. For an important family of channels the capacity is given by a simple optimization problem as proven in Shannon's noisy coding theorem. Furthermore, for these channels, we have the Blahut-Arimoto algorithm that allows to efficiently solve the optimization problem and compute the capacity. In groundbreaking work, Verdu and Han proved a coding theorem for general channels. However, despite considerable effort, there is no equivalent to the Blahut-Arimoto algorithm for computing the generalized capacity. Here, we show that such an algorithm can not exist.
