A polynomial time approximation scheme (PTAS) for an optimization problem A is an algorithm that given in input an instance of A and E > 0 find;,; (1 + E)-approximate solution in time that is polynomial for each fixed E. Typical running times are no(+) or 2"' n. While algorithms of the former kind t
Abstracl. For a number of computational search problems, the existence of a polynomial-time algorithm for the problem implies that a polynomial-time algorithm for the problem is constructively known. Some instances of such self-witnessing polynomial-lime complexity are presented. Our main resuk demo
