Approximation Algorithms for the Traveling Salesperson Problem

Approximation Algorithms for the Traveling Salesperson Problem. Approximation Algorithm. Up to now, the best algorithm for solving an NP-complete problem requires exponential time in the worst case. It is too time-consuming.

Rooting a tree

Rooting a tree. For doing any tree computation, we need to know the parent p ( v ) for each node v . Hence, we need to root the tree at a vertex r . We first construct an Euler tour and for the vertex r , set s (< u d -1 , r >) = 0 . u d -1 is the last vertex adjacent to r .
