Perhaps you should try some spelling variations:
"based sampling algorithm" » "based making algorithm" (Expand Search), "based modeling algorithm" (Expand Search), "based mining algorithm" (Expand Search)
"data routing algorithm" » "data modeling algorithm" (Expand Search), "data finding algorithm" (Expand Search), "data making algorithm" (Expand Search), "data groupings algorithm" (Expand Search), "data relating algorithm" (Expand Search), "data using 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)

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