- Is this true? I am not aware of any decent algorithms for Travelling
- Salesman at all. In fact G&J show that there cannot be any polynomial
- time approximation algorithms for Travelling Salesman that achieve
- ANY given multiple of the optimal solution (page 147).
- Does this not contradict the above statement, or am I labouring under a
- delusion?
