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)
"elements under algorithm" » "elements new algorithm" (Expand Search), "elements tide algorithm" (Expand Search), "elements other algorithms" (Expand Search), "elements tended algorithm" (Expand Search)
"element four algorithms" » "element group algorithms" (Expand Search), "element ore algorithms" (Expand Search), "element fbe algorithms" (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 under algorithm") OR ("element four algorithms"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements under algorithm\") OR (\"element four algorithms\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements under algorithm ) OR ( element four algorithms ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements under algorithm") OR ("element four algorithms"))) OR ("element sampling algorithm"))*.
