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