Perhaps you should try some spelling variations:
"linac based basis optimization algorithm" » "linac based based optimization algorithm" (Expand Search), "linac based hawks optimization algorithm" (Expand Search), "linac based rabbits optimization algorithm" (Expand Search), "lina based basis optimization algorithm" (Expand Search)
"binary data process optimization algorithm" » "binary batch process optimization algorithm" (Expand Search), "binary water process optimization algorithm" (Expand Search), "binary due process optimization algorithm" (Expand Search), "binary rat process optimization algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("linac based basis optimization algorithm") OR ("binary data process optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"linac based basis optimization algorithm\") OR (\"binary data process optimization algorithm\"))".
• Removing quotes may allow a broader search: (( linac based basis optimization algorithm ) OR ( binary data process optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("linac based basis optimization algorithm") OR ("binary data process optimization algorithm"))*.
