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)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas 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 ("movement data algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop tree algorithms\") OR (\"movement data algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( develop tree algorithms ) OR ( movement data algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop tree algorithms") OR ("movement data algorithm"))) OR ("data using algorithm"))*.
