Abstract

This paper proves that for every positive integers n and k, we can explicitly construct a graph G with n+O(k) vertices and maximum degree 3, such that even after removing any k vertices from G, the remaining graph still contains a path of length n-1. This settles a problem raised by Zhang [11, 12] in connection with the design of fault-tolerant linear arrays.
