Perhaps you should try some spelling variations:
"implement routing algorithm" » "implement routine algorithm" (Expand Search), "implement modeling algorithm" (Expand Search), "implement finding algorithm" (Expand Search), "implement making algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"element each algorithm" » "element search algorithm" (Expand Search), "element means algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 data algorithms") OR ("element each algorithm"))) OR ("implement routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithms\") OR (\"element each algorithm\"))) OR (\"implement routing algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithms ) OR ( element each algorithm ))) OR ( implement routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithms") OR ("element each algorithm"))) OR ("implement routing algorithm"))*.
