Perhaps you should try some spelling variations:
"elements matching algorithm" » "elements making algorithm" (Expand Search), "elements modeling algorithm" (Expand Search), "elements mining algorithm" (Expand Search), "elements within algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas algorithm" (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: (((("elements matching algorithm") OR ("movement data algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements matching algorithm\") OR (\"movement data algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements matching algorithm ) OR ( movement data algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements matching algorithm") OR ("movement data algorithm"))) OR ("level coding algorithm"))*.
