Perhaps you should try some spelling variations:
"linac based dog optimization algorithm" » "linac based _ optimization algorithm" (Expand Search), "linac based igdt optimization algorithm" (Expand Search), "linac based iot optimization algorithm" (Expand Search), "linac cased dog 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary base based optimization algorithm\") OR (\"linac based dog optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary base based optimization algorithm ) OR ( linac based dog optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary base based optimization algorithm") OR ("linac based dog optimization algorithm"))*.
