Perhaps you should try some spelling variations:
"binary class b optimization algorithm" » "binary class _ optimization algorithm" (Expand Search), "binary class dog optimization algorithm" (Expand Search), "binary class igdt optimization algorithm" (Expand Search)
"binary class based optimization algorithm" » "binary class _ased 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 class based optimization algorithm") OR ("binary class b optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary class based optimization algorithm\") OR (\"binary class b optimization algorithm\"))".
• Removing quotes may allow a broader search: (( binary class based optimization algorithm ) OR ( binary class b optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("binary class based optimization algorithm") OR ("binary class b optimization algorithm"))*.
