Perhaps you should try some spelling variations:
"data routing algorithm" » "data modeling algorithm" (Expand Search), "data finding algorithm" (Expand Search), "data making algorithm" (Expand Search), "data groupings algorithm" (Expand Search), "data relating algorithm" (Expand Search), "data using algorithm" (Expand Search)
"develop tree algorithms" » "develop three algorithms" (Expand Search), "develop art algorithms" (Expand Search), "develop two algorithms" (Expand Search), "develop new algorithms" (Expand Search), "develop targeted algorithms" (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: (((("develop tree algorithms") OR ("relevant data algorithms"))) OR ("data routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop tree algorithms\") OR (\"relevant data algorithms\"))) OR (\"data routing algorithm\"))".
• Removing quotes may allow a broader search: (((( develop tree algorithms ) OR ( relevant data algorithms ))) OR ( data routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop tree algorithms") OR ("relevant data algorithms"))) OR ("data routing algorithm"))*.
