Perhaps you should try some spelling variations:
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"element mlm algorithm" » "element rl algorithm" (Expand Search), "element em algorithm" (Expand Search), "element svm algorithm" (Expand Search), "element mesh 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: (((("element mlm algorithm") OR ("element method algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mlm algorithm\") OR (\"element method algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( element mlm algorithm ) OR ( element method algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mlm algorithm") OR ("element method algorithm"))) OR ("data using algorithm"))*.
