LAW2ORDER selects diverse, promising batches for expensive permutation optimization. It weights a determinantal point process kernel by acquisition values, then greedily fills each batch with high-variance candidates and evaluates them in parallel. On TSP-burma14, LAW-EST reports cost 3369 ± 7 versus 3786 ± 74 for unweighted DPP-MAX-EST, with batch size 5 over 15 runs. LAW-EST is competitive across problems, but other methods lead on some benchmarks.
