| $380{,}092$ | From Yue Huang (University of Notre Dame). Briefly, the method starts from the published solution and combines randomized near-optimal exact-cover restarts, short HGS descents in PyVRP, and exact CP-SAT recombination over a pool of 3,456 distinct routes. The search was orchestrated by Poolish, an internally developed autonomous optimization agent; every candidate was scored by a frozen, solver-independent verifier. |
