- | The euclidean distances are computed using **double** data type in C++ which is safe for a single computation within 18 decimal digits (GNU GCC 4.0+). Our rule to check if a route is valid is as follows: the travel length is computed in the order of clients that appear in the route and this value should be inferior or equal to the travel length limit (Tmax value in Chao's instances). | + | The euclidean distances are computed using **double** data type in C++ which is safe for a single computation within 18 decimal digits (GNU GCC 4.0+).
