Perhaps you should try some spelling variations:
"binary data level optimization algorithm" » "binary data global optimization algorithm" (Expand Search), "binary rat level optimization algorithm" (Expand Search)
"binary same based optimization algorithm" » "binary states based optimization algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary data level optimization algorithm\") OR (\"binary same based optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary data level optimization algorithm ) OR ( binary same based optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary data level optimization algorithm") OR ("binary same based optimization algorithm"))*.
