Perhaps you should try some spelling variations:
"binary image based optimization algorithm" » "binary image bayesian optimization algorithm" (Expand Search)
"binary task whale optimization algorithm" » "binary task swarm optimization algorithm" (Expand Search), "binary mask whale optimization algorithm" (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: (("binary image based optimization algorithm") OR ("binary task whale optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary image based optimization algorithm\") OR (\"binary task whale optimization algorithm\"))".
• Removing quotes may allow a broader search: (( binary image based optimization algorithm ) OR ( binary task whale optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("binary image based optimization algorithm") OR ("binary task whale optimization algorithm"))*.
