WebThis paper proposes a LP with 3n 2 + 2n constraints only for the directed BWTSP in such a way that, by reducing the problem to an asymmetric traveling salesman problem (ATSP), we add n 2 cardinality constraints and n 2 length constraints to the existing Gavish-Grave LP for the ATSP. The new LP is also valid for the undirected BWTSP when viewed ... GG is a single-commodity flow formulation, where subtours are broken by introducing n ( n − 1) nonnegative variables g ij ( i = 2, \ldots, n;\, j = 1, \ldots, n ). GG consists of constraints ( 1 )– ( 3 ), ( 5) and the following constraints: \sum_ {j=1}^n g_ {ij} - \sum_ {j=2}^n g_ {ji} = 1, \quad i = 2,\ldots,n, (11) WebJan 1, 2024 · This study constitutes of the comparison of mathematical formulations which are already exist in the literature with the formulations which have new adaptations for sub-tour elimination constraints. ...
