Perhaps you should try some spelling variations:
"element sampling algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "client sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "element samplin_ algorithm" (Expand Search), "element samplinb algorithm" (Expand Search), "element samplingnb algorithm" (Expand Search)
"implement routine algorithm" » "implement routing algorithm" (Expand Search), "implement cosine algorithm" (Expand Search), "implement retinex algorithm" (Expand Search)
"element g algorithm" » "element _ algorithm" (Expand Search), "element b algorithm" (Expand Search), "element gnb algorithm" (Expand Search), "elements _ 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 g algorithm") OR ((("implement routine algorithm") OR ("element sampling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element g algorithm\") OR (((\"implement routine algorithm\") OR (\"element sampling algorithm\"))))".
• Removing quotes may allow a broader search: (( element g algorithm ) OR ((( implement routine algorithm ) OR ( element sampling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element g algorithm") OR ((("implement routine algorithm") OR ("element sampling algorithm"))))*.
