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