GeoPAS: Geometric Probing for Algorithm Selection in Continuous Black-Box Optimization

arXiv:2604.09095v3 Announce Type: replace Abstract: Automated algorithm selection for continuous black-box optimization depends on representing problem information under limited probing and selecting solvers under heavy-tailed performance distributions. This paper proposes a geometric probing framework that represents each problem instance by randomly sampled multi-scale two-dimensional slices of the objective landscape. The slices are encoded with validity-mask-aware visual pooling and aggregated into an instance representation. Solver selection is then performed by a logarithmic composite sc
