Boundary effects in the traveling salesperson problem. (English) Zbl 0814.90126

Summary: Consider a subset \(F\) of \([0,1]^ 2\) that is generated by a Poisson point process of constant intensity \(\lambda\). Denote by \(\theta(\lambda)\) the expected length of the shortest tour through \(F\). We prove that for \(\lambda\) large enough, we have \(c\sqrt\lambda+ 1/K\leq \theta(\lambda)\leq c\sqrt\lambda+ K\), where \(c\), \(K\) are universal constants. This settles a conjecture of Karp.
