Perhaps you should try some spelling variations:
"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)
"implement finding algorithm" » "implement findings 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 ("element study algorithm"))) OR ("implement finding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"movement data algorithm\") OR (\"element study algorithm\"))) OR (\"implement finding algorithm\"))".
• Removing quotes may allow a broader search: (((( movement data algorithm ) OR ( element study algorithm ))) OR ( implement finding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("movement data algorithm") OR ("element study algorithm"))) OR ("implement finding algorithm"))*.
