Perhaps you should try some spelling variations:
"elemental mapping algorithm" » "elemental making algorithm" (Expand Search), "elemental mining algorithm" (Expand Search), "elemental learning algorithm" (Expand Search), "elements mapping algorithm" (Expand Search)
"element based algorithm" » "engagement based algorithm" (Expand Search)
"element ree algorithm" » "element tree algorithms" (Expand Search), "element new algorithm" (Expand Search), "element rf algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements res algorithm" (Expand Search), "element te algorithm" (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: (((("element based algorithm") OR ("element ree algorithm"))) OR ("elemental mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithm\") OR (\"element ree algorithm\"))) OR (\"elemental mapping algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithm ) OR ( element ree algorithm ))) OR ( elemental mapping algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithm") OR ("element ree algorithm"))) OR ("elemental mapping algorithm"))*.
