Perhaps you should try some spelling variations:
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"element both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element data algorithms" (Expand Search), "element te algorithms" (Expand Search), "element mesh 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 ((("element mapping algorithm") OR ("element both algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data using algorithm\") OR (((\"element mapping algorithm\") OR (\"element both algorithms\"))))".
• Removing quotes may allow a broader search: (( data using algorithm ) OR ((( element mapping algorithm ) OR ( element both algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data using algorithm") OR ((("element mapping algorithm") OR ("element both algorithms"))))*.
