Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"element tide algorithm" » "element td3 algorithm" (Expand Search), "element leiden algorithm" (Expand Search), "element five algorithms" (Expand Search), "element te algorithm" (Expand Search), "element model algorithm" (Expand Search), "element study 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: (((("relevant data algorithm") OR ("element tide algorithm"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"element tide algorithm\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( element tide algorithm ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("element tide algorithm"))) OR ("image processing algorithm"))*.
