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