Abstract

We present randomized approximation algorithms for multi-criteria Max-TSP. For Max-STSP with k > 1 objective functions, we obtain an approximation ratio of \frac 1k - e\frac 1k - \varepsilon for arbitrarily small ε> 0. For Max-ATSP with k objective functions, we obtain a ratio of \frac1k+1 - e\frac{1}{k+1} - \varepsilon .
