Differential approximation results for the traveling salesman and related problems

We first prove that the minimum and maximum traveling salesman prob- lems, their metric versions as well as some versions defined on parameterized triangle inequalities

Other variants of the maximum traveling salesman problem that have been considered are among others: the maximum symmetric traveling salesman problem (MAX TSP), in which the

Now, consider the optimum TSP tour through all the points of Si Construct a giant closed path visiting every point in S at least once, by substituting into this TSP tour the loops

We present the first polynomial-time approximation schemes (PTASes) for the following subset-connectivity problems in edge-weighted graphs of bounded genus: Steiner

The biofilm may vary depending on the used strains, culture time, and chemical additives present in the culture media (Lee, Gu, Kafle, Catchmark, & Kim, 2015), but it is

It was demonstrated that the fungal treatment improved the dimensional stability of both Norway spruce and sycamore, but also increased their moisture adsorption capacity..
