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