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