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)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithm" (Expand Search), "element ree algorithm" (Expand Search)
"implement finding algorithm" » "implement findings 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 rf algorithm") OR ("element method algorithm"))) OR ("implement finding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element rf algorithm\") OR (\"element method algorithm\"))) OR (\"implement finding algorithm\"))".
• Removing quotes may allow a broader search: (((( element rf algorithm ) OR ( element method algorithm ))) OR ( implement finding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element rf algorithm") OR ("element method algorithm"))) OR ("implement finding algorithm"))*.
