Perhaps you should try some spelling variations:
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element study algorithm" » "element wsindy algorithm" (Expand Search), "element td3 algorithm" (Expand Search), "element seu algorithm" (Expand Search), "relevant study algorithm" (Expand Search), "present study algorithm" (Expand Search), "recent study 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: (("element study algorithm") OR ((("data modeling algorithm") OR ("data clustering algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element study algorithm\") OR (((\"data modeling algorithm\") OR (\"data clustering algorithm\"))))".
• Removing quotes may allow a broader search: (( element study algorithm ) OR ((( data modeling algorithm ) OR ( data clustering algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element study algorithm") OR ((("data modeling algorithm") OR ("data clustering algorithm"))))*.
