Differential approximation results for the traveling salesman problem with distances 1 and 2

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

The weak connected vertex cover problem is as hard as the vertex cover problem in hy- pergraphs since starting from any hypergraph H = (V, E ) and by adding a new hyper- edge

We suppose that we know that the solutions of the planar isoperimetric problem are circles. We consider a very old variant of this problem called Dido’s problem [18]. It is related

term cognitive style is intended to describe the case where an individual's response to information-processing and problem-solving is consistently in a particular mode... That
