摘要：

We consider the long standing puzzle of how to obtain meaningful probabilities in eternal inflation. We demonstrate a new algorithm for computing the probability distribution of pocket universe types, given a multivacua inflationary potential. The computed probability distribution is finite and manifestly gauge independent. We argue that in some scenarios this technique can be applied to disfavour some eternally inflating potentials.
