Perhaps you should try some spelling variations:
"binary task required optimization algorithm" » "binary task inspired optimization algorithm" (Expand Search)
"binary tree based optimization algorithm" » "binary three based optimization algorithm" (Expand Search), "binary free based 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 tree based optimization algorithm") OR ("binary task required optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary tree based optimization algorithm\") OR (\"binary task required optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( binary tree based optimization algorithm ) OR ( binary task required optimization algorithm ))*.
