Perhaps you should try some spelling variations:
"present routing algorithm" » "present cosine algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"recent data algorithm" » "recent jaya algorithm" (Expand Search), "recent deer algorithm" (Expand Search)

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 ("present routing algorithm"))) OR ("recent data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"present routing algorithm\"))) OR (\"recent data algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( present routing algorithm ))) OR ( recent data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("present routing algorithm"))) OR ("recent data algorithm"))*.
