Report on article The Travelling Salesman Problem: A Linear Programming   Formulation
  This article describes counter example prepared in order to prove that linear formulation of TSP problem proposed in [arXiv:0803.4354] is incorrect (it applies also to QAP problem formulation in [arXiv:0802.4307]). Article refers not only to model itself, but also to ability of extension of proposed model to be correct.
