Perhaps you should try some spelling variations:
"data modelling algorithm" » "data modeling algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"data clustering algorithm" » "deep clustering algorithm" (Expand Search), "spatial clustering algorithm" (Expand Search), "dbscan clustering 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 ("data modelling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data clustering algorithm\") OR (\"data modelling algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data clustering algorithm ) OR ( data modelling algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data clustering algorithm") OR ("data modelling algorithm"))) OR ("element method algorithm"))*.
