Perhaps you should try some spelling variations:
"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 algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"data finding algorithm" » "path finding algorithm" (Expand Search), "data fitting algorithm" (Expand Search), "case 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: (((("develop tree algorithms") OR ("relevant data algorithm"))) OR ("data finding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop tree algorithms\") OR (\"relevant data algorithm\"))) OR (\"data finding algorithm\"))".
• Removing quotes may allow a broader search: (((( develop tree algorithms ) OR ( relevant data algorithm ))) OR ( data finding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop tree algorithms") OR ("relevant data algorithm"))) OR ("data finding algorithm"))*.
