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