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)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"element de algorithms" » "element mdem algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element te algorithms" (Expand Search), "elements fe algorithms" (Expand Search), "element fbe 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: (((("relevant data algorithm") OR ("element de algorithms"))) OR ("element mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"element de algorithms\"))) OR (\"element mapping algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( element de algorithms ))) OR ( element mapping algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("element de algorithms"))) OR ("element mapping algorithm"))*.
