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