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 novel algorithm" » "elements forest algorithm" (Expand Search), "elements over algorithm" (Expand Search), "element model algorithm" (Expand Search), "elements involved algorithm" (Expand Search)
"elements new algorithm" » "elements _ algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements fe algorithm" (Expand Search), "elements res 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 novel algorithm") OR ("elements new algorithm"))) OR ("effects sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements novel algorithm\") OR (\"elements new algorithm\"))) OR (\"effects sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements novel algorithm ) OR ( elements new algorithm ))) OR ( effects sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements novel algorithm") OR ("elements new algorithm"))) OR ("effects sampling algorithm"))*.
