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