Perhaps you should try some spelling variations:
"implement learner algorithm" » "implement learning algorithm" (Expand Search), "implement learning algorithms" (Expand Search), "implement search algorithm" (Expand Search)
"recent study algorithm" » "recent wsindy algorithm" (Expand Search), "recent td3 algorithm" (Expand Search), "recent seu algorithm" (Expand Search), "present study algorithm" (Expand Search), "recent studies 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 ("recent study algorithm"))) OR ("implement learner algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"movement data algorithm\") OR (\"recent study algorithm\"))) OR (\"implement learner algorithm\"))".
• Removing quotes may allow a broader search: (((( movement data algorithm ) OR ( recent study algorithm ))) OR ( implement learner algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("movement data algorithm") OR ("recent study algorithm"))) OR ("implement learner algorithm"))*.
