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