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