Researchers have developed a novel unsupervised multi-kernel learning approach for automated algorithm selection in black-box optimization. This method groups problem instances based on heterogeneous landscape representations without relying on performance labels during the clustering phase. The approach utilizes a multi-kernel k-means formulation to learn cluster assignments and kernel weights across four different landscape views: ELA, DeepELA, DoE2Vec, and TransOptAS. Evaluations on differential evolution and particle swarm optimization tasks demonstrated that this unsupervised method achieves strong performance, particularly for differential evolution, and remains competitive with leading baselines for particle swarm optimization.
