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), "elements method algorithm" (Expand Search)
"levels using algorithms" » "levels pacing algorithms" (Expand Search), "levels nine algorithms" (Expand Search), "levels sorting algorithms" (Expand Search), "levels routing algorithms" (Expand Search), "levels fusion algorithms" (Expand Search), "levels making algorithms" (Expand Search), "level using algorithms" (Expand Search), "models using algorithms" (Expand Search), "cells using algorithms" (Expand Search)
"data using algorithm" » "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search), "data making 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 method algorithm") OR ("levels using algorithms"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"levels using algorithms\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( levels using algorithms ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("levels using algorithms"))) OR ("data using algorithm"))*.
