Perhaps you should try some spelling variations:
"data routing algorithm" » "data cosine algorithm" (Expand Search), "data using algorithm" (Expand Search)
"elements method algorithm" » "elements mould algorithm" (Expand Search)
"elements each algorithm" » "elements search algorithm" (Expand Search), "elements jaya 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: (((("elements method algorithm") OR ("elements each algorithm"))) OR ("data routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithm\") OR (\"elements each algorithm\"))) OR (\"data routing algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithm ) OR ( elements each algorithm ))) OR ( data routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithm") OR ("elements each algorithm"))) OR ("data routing algorithm"))*.
