Perhaps you should try some spelling variations:
"effects sampling algorithm" » "effects mining algorithm" (Expand Search), "effects modeling algorithm" (Expand Search), "effects along algorithm" (Expand Search), "effects arising algorithm" (Expand Search)
"elements under algorithm" » "elements new algorithm" (Expand Search), "elements other algorithms" (Expand Search), "elements kepler algorithm" (Expand Search), "elements tended algorithm" (Expand Search)
"elements tide algorithm" » "elements td3 algorithm" (Expand Search), "elements leiden algorithm" (Expand Search), "elements five algorithms" (Expand Search), "elements tended algorithm" (Expand Search), "element te algorithm" (Expand Search), "elements ree 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: (((("elements under algorithm") OR ("elements tide algorithm"))) OR ("effects sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements under algorithm\") OR (\"elements tide algorithm\"))) OR (\"effects sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements under algorithm ) OR ( elements tide algorithm ))) OR ( effects sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements under algorithm") OR ("elements tide algorithm"))) OR ("effects sampling algorithm"))*.
