Perhaps you should try some spelling variations:
"improvements can algorithm" » "improvements make algorithm" (Expand Search), "improvements _ algorithm" (Expand Search), "improvement gap algorithm" (Expand Search), "improvements cnn algorithm" (Expand Search), "improvements mean algorithm" (Expand Search), "improvements coa algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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: (((("improvements can algorithm") OR ("relevant data algorithms"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"improvements can algorithm\") OR (\"relevant data algorithms\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( improvements can algorithm ) OR ( relevant data algorithms ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("improvements can algorithm") OR ("relevant data algorithms"))) OR ("data using algorithm"))*.
