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