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