Average-case Complexity

  title={Average-case Complexity},
  author={Luca Trevisan},
  journal={2008 49th Annual IEEE Symposium on Foundations of Computer Science},
We review the many open questions and the few things that are known about the average-case complexity of computational problems. We shall follow the presentations of Impagliazzo, of Goldreich, and of Bogdanov and the author, and focus on the following subjects. (i). Average-case tractability. What does it mean for a problem to have an "efficient on average'' algorithm with respect to a distribution of instances? There is more than one ``correct'' answer to this question, and a numberof… CONTINUE READING
