Perhaps you should try some spelling variations:
"element sampling algorithm" » "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"effects models algorithm" » "effects modeling algorithm" (Expand Search), "effects novel algorithm" (Expand Search), "effects modbo algorithm" (Expand Search), "effects model algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh 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 means algorithm") OR ("element sampling algorithm"))) OR ("effects models algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element means algorithm\") OR (\"element sampling algorithm\"))) OR (\"effects models algorithm\"))".
• Removing quotes may allow a broader search: (((( element means algorithm ) OR ( element sampling algorithm ))) OR ( effects models algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element means algorithm") OR ("element sampling algorithm"))) OR ("effects models algorithm"))*.
