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