Perhaps you should try some spelling variations:
"data processing algorithm" » "data modeling algorithm" (Expand Search), "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "image processing 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)
"movement data algorithms" » "movement art algorithms" (Expand Search), "movement all algorithms" (Expand Search), "movement 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 ("movement data algorithms"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop tree algorithms\") OR (\"movement data algorithms\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( develop tree algorithms ) OR ( movement data algorithms ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop tree algorithms") OR ("movement data algorithms"))) OR ("data processing algorithm"))*.
