We study the hardness of approximation for the MINIMUM HACKING problem, which roughly can be described as the problem of finding the best way to compromise some target nodes given a few initial compromised nodes in a network. We give three reductions to show that MINIMUM HACKING is not approximable to within where , for any ! " $#% . In particular, the reductions are from a PCP, from the MINIMU...

We also present two cases were SClib has been used. In the first set of applications we use SClib to write a port to Python...
