Perhaps you should try some spelling variations:
bayesian optimization » based optimization (Expand Search)
whale optimization » swarm optimization (Expand Search)
library based » laboratory based (Expand Search)
risk bayesian » task bayesian (Expand Search)
based whale » based whole (Expand Search), baleen whale (Expand Search), based halide (Expand Search)
binary risk » primary risk (Expand Search), dietary risk (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( library based whale optimization algorithm ) OR ( binary risk bayesian optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( library based whale optimization algorithm ) OR ( binary risk bayesian optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( library based whale optimization algorithm ) OR ( binary risk bayesian optimization algorithm ))*.
