Abstract
For every ε{lunate} > 0 and every integer m > 0, we construct explicitly graphs with O (m / ε{lunate}) vertices and maximum degree O (1 / ε{lunate}2), such that after removing any (1 - ε{lunate}) portion of their vertices or edges, the remaining graph still contains a path of length m. This settles a problem of Rosenberg, which was motivated by the study of fault tolerant linear arrays.
