Perhaps you should try some spelling variations:
"elements mapping algorithm" » "elements making algorithm" (Expand Search), "elements mining algorithm" (Expand Search), "elements learning algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "elements during algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 ("element method algorithm"))) OR ("elements mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"movement data algorithm\") OR (\"element method algorithm\"))) OR (\"elements mapping algorithm\"))".
• Removing quotes may allow a broader search: (((( movement data algorithm ) OR ( element method algorithm ))) OR ( elements mapping algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("movement data algorithm") OR ("element method algorithm"))) OR ("elements mapping algorithm"))*.
