WebJun 12, 2024 · I'm wondering if the normal Dijkstra algorithm (Greedy + Relaxation) still applies in the case. Because we don't know the full graph, the shortest path to a node might haven't been explored yet, and exist in the unknown part. (That's my biggest concern). I hope my explanations are clear enough, thank you very much! Webponent.

"Linear programming relaxation is a standard technique for designing approximation algorithms for hard optimization problems. In this application, an important concept is the integrality gap, the maximum ratio between the solution quality of the integer program and of its relaxation. In an instance of a minimization problem, if the real minimum (the minimum of the integer problem) is , and the relaxed minimum (the minimum of the linear programming relaxation) is , then the integr… " - Greedy relaxation
