On the Theory of Average Case Complexity
This paper takes the next step in developing the theory of average case complexity initiated by Leonid A Levin. Previous works Levin 84, Gurevich 87, Venkatesan and Levin 88] have...

If NP Languages are Hard on the Worst-Case Then It is Easy to Find Their Hard Instances
We prove that if NP ⊆ BPP, i.e., if SAT is worst-case hard, then for every probabilistic polynomial-time algorithm trying to decide SAT, there exists some polynomially samplable ...

A Fuzzy Approach for Variation Aware Buffer Insertion and Driver Sizing
In nanometer regime, the effects of process variations are dominating circuit performance, power and reliability of circuits. Hence, it is important to properly manage variation e...
