A new research paper published on arXiv investigates the effectiveness of test-time budget allocation for neural combinatorial optimization solvers. The study found that while uniform sampling appears to show gains on in-distribution workloads, these gains are often illusory and indistinguishable from zero when measured accurately. However, under distribution shift, a non-uniform allocation guided by held-out sample statistics demonstrated a real improvement in best-of-k solutions. AI
