Perhaps you should try some spelling variations:
"data backing algorithm" » "data tracking algorithm" (Expand Search), "data making algorithm" (Expand Search), "data tracking algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"movement data algorithms" » "movement art algorithms" (Expand Search), "movement all algorithms" (Expand Search), "movement both algorithms" (Expand Search)

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 algorithms") OR ("element method algorithm"))) OR ("data backing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"movement data algorithms\") OR (\"element method algorithm\"))) OR (\"data backing algorithm\"))".
• Removing quotes may allow a broader search: (((( movement data algorithms ) OR ( element method algorithm ))) OR ( data backing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("movement data algorithms") OR ("element method algorithm"))) OR ("data backing algorithm"))*.
