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 algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"element cc3d algorithm" » "element cscap algorithm" (Expand Search), "element cnn algorithm" (Expand Search), "element wold 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 algorithms") OR ("element cc3d algorithm"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithms\") OR (\"element cc3d algorithm\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithms ) OR ( element cc3d algorithm ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithms") OR ("element cc3d algorithm"))) OR ("image processing algorithm"))*.
