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