An approximation algorithm is an algorithm that finds an approximate solution to a (typically NP-hard) problem. The quality of the algorithm is measured by how close to the actual optimum it performs. For example, it is a constant factor approximation algorithm if it always outputs a solution that is within a constant factor of the optimum. Hardness of approximation is one way to separate NP-hard problems.

It seems this question is NP-Complete.
The general idea:
In a graph which is a 3-regular graph minus an edge,
a spanning tree that minimizes $\max x_i$ is (more or less) an Hamiltonian Pa …
