Cover Story: Using LLM Architectures and training algorithms, we attempt to explore a possible one-shot solution to the fundamental NP-hard problem of combinatorial optimization, in particular, the Traveling Salesman Problem (TSP). Similar to the LLM design, which is trained in an autoregressive manner to predict the next token, our model is trained to predict the next node in a TSP graph. After the model is trained on random TSP graphs with known near-optimal solutions, we fine-tune the model using Direct Preference Optimization (DPO). The tour generation in a trained model is autoregressive one-step generation with no need for iterative refinement. Our results are very promising, indicating that a small amount of training data yields solutions within a few percent of the optimal. This optimization improves if more data are used to train the model. View this paper
