Extensions of Karger's Algorithm: Why They Fail in Theory and How They Are Useful in Practice
We prove impossibility results showing that Karger’s contraction algorithm cannot be extended to $s$-$t$-mincuts or normalized cuts. However, we show how extensions of Karger’s algorithm can still be useful for seeded segmentation.
