Congratulations to Yudi on your first paper (with me) and on the honor! This work, as part of the CAMPR project supported by NSF, revisited the problem of localizing failed links (i.e., transmission lines) in a power grid under joint cyber-physical attack. But unlike previous works that assumed the grid to remain connected after the attack, we consider a more general scenario with a possibly partitioned grid and the resulting (unknown) changes in the power injections within the attacked area.
