The Complexity of Euclidian 2 Dimension Travelling Salesman Problem   versus General Assign Problem, NP is not P
  This paper presents the differences between two NP problems. It focuses in the Euclidian 2 Dimension Travelling Salesman Problems and General Assign Problems. The main results are the triangle reduction to verify the solution in polynomial time for the former and for the later the solution to the Noted Conjecture of the NP-Class, NP is not P.
