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)
"space modeling algorithm" » "space making algorithm" (Expand Search), "space model algorithm" (Expand Search), "space models algorithm" (Expand Search), "case modeling 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: (((("space modeling algorithm") OR ("image processing algorithm"))) OR ("element data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"space modeling algorithm\") OR (\"image processing algorithm\"))) OR (\"element data algorithm\"))".
• Removing quotes may allow a broader search: (((( space modeling algorithm ) OR ( image processing algorithm ))) OR ( element data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("space modeling algorithm") OR ("image processing algorithm"))) OR ("element data algorithm"))*.
