Is there also a known relationship between the actual polynomial time cost

algorithm exists?

Just curious.

According to the Wikipedia article on TSP, there is a polynomial time
that gets within 1+1/N in time O(n (log n)^O(N).

Here's the paper Wikipedia cites:

That page has a download link for the paper.
