Perhaps you should try some spelling variations:
"relevant graph algorithms" » "relevant art algorithms" (Expand Search), "relevant each algorithm" (Expand Search), "relevant rl algorithms" (Expand Search), "relevant gray algorithms" (Expand Search), "relevant trade algorithms" (Expand Search), "relevant grey algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding 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: (("relevant graph algorithms") OR ((("element method algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant graph algorithms\") OR (((\"element method algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant graph algorithms ) OR ((( element method algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant graph algorithms") OR ((("element method algorithm") OR ("neural coding algorithm"))))*.
