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