摘要
For paths P-n, Chartrand, Nebesky and Zhang gave the exact value of ac'(P-n) for n <= 8, and showed that ac'(P-n) <= (n-2 2) + 2 for every positive integer n, where ac'(P-n) denotes the nearly antipodal chromatic number of P-n. In this paper, we determine the exact values of ac'(P-n) for all even integers n >= 8.
