A new paper evaluates four leading landscape feature representations used in black-box optimization, including ELA, DeepELA, TransOptAS, and DoE2Vec. The study found that each representation organizes problem spaces differently, with ELA and TransOptAS forming compact geometric structures, DeepELA offering a balanced view, and DoE2Vec showing semantic alignment but fragmentation. The research indicates that these representations capture complementary aspects of problem landscapes and suggests that no single representation can fully align structural descriptions with observed algorithm performance.
