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