Perhaps you should try some spelling variations:
"fragment based algorithms" » "fragment based algorithm" (Expand Search), "agent based algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding 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: (("fragment based algorithms") OR ((("relevant data algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"fragment based algorithms\") OR (((\"relevant data algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( fragment based algorithms ) OR ((( relevant data algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("fragment based algorithms") OR ((("relevant data algorithms") OR ("neural coding algorithm"))))*.
