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 present algorithm" » "elements presented algorithm" (Expand Search), "elements treatment algorithm" (Expand Search), "elements forest algorithm" (Expand Search)
"element te algorithm" » "element tide algorithm" (Expand Search), "element new algorithm" (Expand Search), "element de algorithms" (Expand Search), "element _ algorithm" (Expand Search), "element g algorithm" (Expand Search), "element data 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: (((("element te algorithm") OR ("elements present algorithm"))) OR ("effects sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element te algorithm\") OR (\"elements present algorithm\"))) OR (\"effects sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element te algorithm ) OR ( elements present algorithm ))) OR ( effects sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element te algorithm") OR ("elements present algorithm"))) OR ("effects sampling algorithm"))*.
