Perhaps you should try some spelling variations:
"space modeling algorithm" » "space making algorithm" (Expand Search), "space model algorithm" (Expand Search), "space models algorithm" (Expand Search), "case modeling algorithm" (Expand Search)
"data clustering algorithm" » "deep clustering algorithm" (Expand Search), "spatial clustering algorithm" (Expand Search), "dbscan clustering 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: (((("data clustering algorithm") OR ("space modeling algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data clustering algorithm\") OR (\"space modeling algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( data clustering algorithm ) OR ( space modeling algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data clustering algorithm") OR ("space modeling algorithm"))) OR ("relevant data algorithm"))*.
