Perhaps you should try some spelling variations:
"image processing algorithm" » "image processing algorithms" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"patient data algorithm" » "patient jaya algorithm" (Expand Search), "patient deer algorithm" (Expand Search), "patient a algorithm" (Expand Search), "patient care 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: (((("element method algorithm") OR ("patient data algorithm"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"patient data algorithm\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( patient data algorithm ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("patient data algorithm"))) OR ("image processing algorithm"))*.
