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