Perhaps you should try some spelling variations:
"movement learning algorithm" » "movement learning algorithms" (Expand Search), "movements training algorithm" (Expand Search), "movement tracking algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element best algorithms" (Expand Search), "element method 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: (((("element means algorithm") OR ("element mesh algorithm"))) OR ("movement learning algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element means algorithm\") OR (\"element mesh algorithm\"))) OR (\"movement learning algorithm\"))".
• Removing quotes may allow a broader search: (((( element means algorithm ) OR ( element mesh algorithm ))) OR ( movement learning algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element means algorithm") OR ("element mesh algorithm"))) OR ("movement learning algorithm"))*.
