Packing Center Record Board

Autonomous campaign on the workstation (CPU workers plus the RTX 4070): 2273 cases in the bank, 1120 search jobs so far, 690 certified improvements to the bank, last job finished 2026-09-12 04:21 UTC. The site is rebuilt and redeployed by the campaign itself every hour.

28 listed values beaten across 2308 certified cases from Erich Friedman's Packing Center. Beaten means our certified value clears the page's displayed digits by at least one unit of the last decimal, so it holds whether the trailing plus means truncated or rounded. Reproduced means we match the listed value within that tolerance. Behind means the listed configuration is still better than ours. Open a family for its full table.
