Beyond Quantum Advantage: Improved Classical Algorithms for the Binary Paint Shop Problem
An arXiv preprint reports improved classical algorithms for the binary paint shop problem, a combinatorial optimization task previously cited as a potential quantum advantage benchmark. The work suggests classical methods can now outperform some known quantum approaches on this problem.

Within two years, quantum optimization benchmarks will drop binary paint shop instances where this classical method is strong, redirecting near-term advantage claims to harder structured problems.
Classical baselines tend to be updated as soon as stronger algorithms are published; if these results are verified, groups testing quantum annealers or QAOA on paint shop instances will need recalibrated benchmarks to avoid comparing against outdated classical limits.
