Perhaps you should try some spelling variations:
"linac case level optimization algorithm" » "linac case global optimization algorithm" (Expand Search), "linac case based optimization algorithm" (Expand Search)
"binary base dog optimization algorithm" » "binary base _ optimization algorithm" (Expand Search), "binary base igdt optimization algorithm" (Expand Search), "binary based dog 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 dog optimization algorithm") OR ("linac case level optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary base dog optimization algorithm\") OR (\"linac case level optimization algorithm\"))".
• Removing quotes may allow a broader search: (( binary base dog optimization algorithm ) OR ( linac case level optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("binary base dog optimization algorithm") OR ("linac case level optimization algorithm"))*.
