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