Perhaps you should try some spelling variations:
"movement tracking algorithm" » "movement learning algorithm" (Expand Search), "movement processing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element tide algorithm" » "element td3 algorithm" (Expand Search), "element leiden algorithm" (Expand Search), "element five algorithms" (Expand Search), "element te algorithm" (Expand Search), "element model algorithm" (Expand Search), "element study 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 tracking algorithm") OR ((("element tide algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"movement tracking algorithm\") OR (((\"element tide algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( movement tracking algorithm ) OR ((( element tide algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("movement tracking algorithm") OR ((("element tide algorithm") OR ("element method algorithm"))))*.
