Abstract

fetched live from OpenAlex

A huge number of papers appeared in the literature which study the well known Traveling Salesman Problem (TSP) and its generalizations to the case of multiple vehicles known as Vehicle Routing Problems (VRPs). While there exists one and only one TSP, many problems belong to the class of VRPs (see Toth, Vigo (2002)). In the TSP and in the VRPs all customers need to be visited. This means that in the situations modeled all customers are known at the time the optimization model is run and all require service. While this is indeed the case in many practical problems, there are many other practical problems where this assumption is not valid. Let us consider the following situation where a set of customers is given and only a subset has to be selected and served. Nowadays it is more and more frequent that shippers post their demands for transportation service on the web, usually in specific databases, and carriers identify some of those demands and offer their service to the shippers. Usually a carrier has a fleet of vehicles and a set of regular customers that have to be served. If the capacity of the vehicles is not fully used, the carrier may wish to look for spot customers on the web. In this case, the carrier has to

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
