The outcome reports what was recorded. Its scope and evidence grade remain separate. Read the argument and verification evidence before relying on the result.

2Authored explanation

Use companion repository commit \(4e725664b35a6e5640876e56b1cd0ec3aeeef6e5\) and set \(n=10\) in \(optimization_models/heilbronn_final.py\). Seed the exact Comellas–Yebra coordinates and value as the incumbent. Retain the proved five-boundary-point canonicalization from Proposition 2. Run the full \(P_\Delta^*\) model over arbitrary ten-point configurations. Leave out the Monji-Modir-Kocuk two-points-per-edge conjecture and \(y_5\le1/2\) restriction.

A first budget is 24 wall-clock hours with at most 16 threads and 64 GiB RAM. Record Python, Gurobi, operating system, CPU, model parameters, deterministic seed, primal and dual bounds, node counts, logs, checkpoints, and the final solver status. Export each incumbent as exact decimal strings and save every certificate or box description needed for independent interval or rational checking.

A universal upper bound of 0.04654 is a useful intermediate result. A timeout or resource limit should become an explicit attempt record with its last certified upper bound. Keep the problem open until a universal exact or rigorous interval upper bound matches the exact construction value.
