Perhaps you should try some spelling variations:
"experiments based algorithm" » "experiments showed algorithm" (Expand Search), "experimental basis algorithm" (Expand Search), "experimental case algorithm" (Expand Search)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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: (((("experiments based algorithm") OR ("relevant data algorithm"))) OR ("data using algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments based algorithm\") OR (\"relevant data algorithm\"))) OR (\"data using algorithms\"))".
• Removing quotes may allow a broader search: (((( experiments based algorithm ) OR ( relevant data algorithm ))) OR ( data using algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments based algorithm") OR ("relevant data algorithm"))) OR ("data using algorithms"))*.
