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)
"movement update algorithm" » "movement pass algorithm" (Expand Search), "movement data algorithms" (Expand Search), "movement ipca algorithm" (Expand Search), "movement data algorithm" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore 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: (("data processing algorithm") OR ((("element tree algorithms") OR ("movement update algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element tree algorithms\") OR (\"movement update algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element tree algorithms ) OR ( movement update algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element tree algorithms") OR ("movement update algorithm"))))*.
