Perhaps you should try some spelling variations:
"linac based model optimization algorithm" » "linac based level optimization algorithm" (Expand Search), "linac based motor optimization algorithm" (Expand Search), "linac based monkey optimizations algorithm" (Expand Search)
"binary case dog optimization algorithm" » "binary case _ optimization algorithm" (Expand Search), "binary case igdt 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 case dog optimization algorithm\") OR (\"linac based model optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary case dog optimization algorithm ) OR ( linac based model optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary case dog optimization algorithm") OR ("linac based model optimization algorithm"))*.
