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