Perhaps you should try some spelling variations:
"based routing algorithm" » "based modeling algorithm" (Expand Search), "based finding algorithm" (Expand Search), "based making algorithm" (Expand Search), "based testing algorithm" (Expand Search), "based dosing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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: (("based routing algorithm") OR ((("relevant data algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based routing algorithm\") OR (((\"relevant data algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( based routing algorithm ) OR ((( relevant data algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("based routing algorithm") OR ((("relevant data algorithm") OR ("element method algorithm"))))*.
