Perhaps you should try some spelling variations:
"effects sampling algorithm" » "effects making algorithm" (Expand Search), "effects modeling algorithm" (Expand Search), "effects mining algorithm" (Expand Search), "effects along algorithm" (Expand Search), "effects arising algorithm" (Expand Search)
"elements group algorithms" » "elements four algorithms" (Expand Search), "elements graph algorithms" (Expand Search), "elements frog algorithms" (Expand Search), "elements groups algorithms" (Expand Search), "element group algorithms" (Expand Search), "events group algorithms" (Expand Search)
"elements ree algorithm" » "elements tree algorithms" (Expand Search), "elements new algorithm" (Expand Search), "elements rf algorithm" (Expand Search), "element ree algorithm" (Expand Search), "elements res algorithm" (Expand Search), "elements fe 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 group algorithms") OR ("elements ree algorithm"))) OR ("effects sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements group algorithms\") OR (\"elements ree algorithm\"))) OR (\"effects sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements group algorithms ) OR ( elements ree algorithm ))) OR ( effects sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements group algorithms") OR ("elements ree algorithm"))) OR ("effects sampling algorithm"))*.
