Perhaps you should try some spelling variations:
"element network algorithm" » "element new algorithm" (Expand Search), "alignment network algorithm" (Expand Search)
"implement routine algorithm" » "implement routing algorithm" (Expand Search), "implement cosine algorithm" (Expand Search), "implement retinex algorithm" (Expand Search)
"elements rf algorithm" » "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements art algorithms" (Expand Search), "elements ree algorithm" (Expand Search), "elements res 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: (((("elements rf algorithm") OR ("element network algorithm"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements rf algorithm\") OR (\"element network algorithm\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( elements rf algorithm ) OR ( element network algorithm ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements rf algorithm") OR ("element network algorithm"))) OR ("implement routine algorithm"))*.
