Perhaps you should try some spelling variations:
"implement routing algorithm" » "implement routine algorithm" (Expand Search), "implement modeling algorithm" (Expand Search), "implement finding algorithm" (Expand Search), "implement making algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"recent both algorithms" » "recent art algorithms" (Expand Search), "recent four algorithms" (Expand Search), "recent box 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 ("recent both algorithms"))) OR ("implement routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"recent both algorithms\"))) OR (\"implement routing algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( recent both algorithms ))) OR ( implement routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("recent both algorithms"))) OR ("implement routing algorithm"))*.
