Perhaps you should try some spelling variations:
"query processing algorithm" » "query modeling algorithm" (Expand Search), "query routing algorithm" (Expand Search), "query tracking algorithm" (Expand Search), "pre processing algorithm" (Expand Search)
"element study algorithm" » "element wsindy algorithm" (Expand Search), "element td3 algorithm" (Expand Search), "element seu algorithm" (Expand Search), "relevant study algorithm" (Expand Search), "present study algorithm" (Expand Search), "recent study algorithm" (Expand Search)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element study algorithm") OR ("movement data algorithm"))) OR ("query processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element study algorithm\") OR (\"movement data algorithm\"))) OR (\"query processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element study algorithm ) OR ( movement data algorithm ))) OR ( query processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element study algorithm") OR ("movement data algorithm"))) OR ("query processing algorithm"))*.
