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