WebMay 18, 1995 · 4. 3-index formulations from Fox, Gavish and Graves (1980) In this section we relate the 3-index formulation of Picard and Queyranne (1978) to the formulations presented by Fox, Gavish and Graves (1980) and show that both, our formulation NO2 as well as 3PQ are going to produce at least as good or better linear bounds. L. WebThere are many sub-tour elimination constraint (SEC) formulations for the traveling salesman problem (TSP). Among the different methods found in articles, usually three apply more than others.

WebApr 3, 2024 · The second model was based on the Gavish and Graves’ formulation (GG) for the TSP where flow constraints prevent subtours. The third model was based on the Dantzig–Fulkerson–Johnson’s (DFJ) formulation for the TSP. The DFJ model has a linear function and quadratic constraints. Linearizations were presented for the quadratic models.
