Perhaps you should try some spelling variations:
"experimental case algorithm" » "experimental mouse algorithm" (Expand Search), "experimental _ algorithm" (Expand Search), "experimental cosine algorithm" (Expand Search), "experimental carlo algorithm" (Expand Search), "experimental jaya algorithm" (Expand Search)
"image 2_using algorithm" » "image cosine algorithm" (Expand Search)
"element data algorithm" » "element jaya algorithm" (Expand Search), "element deer algorithm" (Expand Search), "elements data 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: (((("experimental case algorithm") OR ("element data algorithm"))) OR ("image 2_using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experimental case algorithm\") OR (\"element data algorithm\"))) OR (\"image 2_using algorithm\"))".
• Removing quotes may allow a broader search: (((( experimental case algorithm ) OR ( element data algorithm ))) OR ( image 2_using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experimental case algorithm") OR ("element data algorithm"))) OR ("image 2_using algorithm"))*.
