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