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