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)
"element method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search), "elements method algorithms" (Expand Search)
"relevant study algorithm" » "relevant wsindy algorithm" (Expand Search), "relevant td3 algorithm" (Expand Search), "relevant seu algorithm" (Expand Search), "relevant studies algorithm" (Expand Search), "recent study 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 method algorithms") OR ("relevant study algorithm"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithms\") OR (\"relevant study algorithm\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithms ) OR ( relevant study algorithm ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithms") OR ("relevant study algorithm"))) OR ("data modeling algorithm"))*.
