On the hardness of approximating Max-Satisfy
Max-Satisfy is the problem of finding an assignment that satisfies the maximum number of equations in a system of linear equations over Q. We prove that unless NPBPP Max-Satisfy c...

Compiling Uncertainty Away: Solving Conformant Planning Problems using a Classical Planner (Sometimes)
Even under polynomial restrictions on plan length, conformant planning remains a very hard computational problem as plan verification itself can take exponential time. This heavy ...

Hardness of fully dense problems
In the past decade, there has been a stream of work in designing approximation schemes for dense instances of NP-Hard problems. These include the work of Arora, Karger and Karpins...

On the Hardness of Range Assignment Problems
We investigate the computational hardness of the Connectivity, the Strong Connectivity and the Broadcast type of Range Assignment Problems in R2 and R3. We present new reductions ...
