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