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)
"study clustering algorithm" » "fuzzy clustering algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te 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: (((("study clustering algorithm") OR ("data modeling algorithm"))) OR ("element mesh algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"study clustering algorithm\") OR (\"data modeling algorithm\"))) OR (\"element mesh algorithm\"))".
• Removing quotes may allow a broader search: (((( study clustering algorithm ) OR ( data modeling algorithm ))) OR ( element mesh algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("study clustering algorithm") OR ("data modeling algorithm"))) OR ("element mesh algorithm"))*.
