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)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"movement data algorithms" » "movement art algorithms" (Expand Search), "movement all algorithms" (Expand Search), "movement both algorithms" (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: (("data using algorithm") OR ((("elements mapping algorithm") OR ("movement data algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data using algorithm\") OR (((\"elements mapping algorithm\") OR (\"movement data algorithms\"))))".
• Removing quotes may allow a broader search: (( data using algorithm ) OR ((( elements mapping algorithm ) OR ( movement data algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data using algorithm") OR ((("elements mapping algorithm") OR ("movement data algorithms"))))*.
