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