Perhaps you should try some spelling variations:
"binary task required optimization algorithm" » "binary task inspired optimization algorithm" (Expand Search)
"binary also guided optimization algorithm" » "binary also spider optimization algorithm" (Expand Search), "binary also based optimization algorithm" (Expand Search), "binary also inspired optimization algorithm" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary task required optimization algorithm\") OR (\"binary also guided optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary task required optimization algorithm ) OR ( binary also guided optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary task required optimization algorithm") OR ("binary also guided optimization algorithm"))*.
