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