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)
"effects making algorithm" » "effects mining algorithm" (Expand Search), "effects tracking algorithm" (Expand Search), "effects matching algorithm" (Expand Search), "effects main algorithm" (Expand Search), "effects using algorithm" (Expand Search), "effects along algorithm" (Expand Search)
"element novel algorithm" » "element forest algorithm" (Expand Search), "element model algorithm" (Expand Search), "present novel algorithm" (Expand Search), "elements over 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 novel algorithm") OR ((("effects sampling algorithm") OR ("effects making algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element novel algorithm\") OR (((\"effects sampling algorithm\") OR (\"effects making algorithm\"))))".
• Removing quotes may allow a broader search: (( element novel algorithm ) OR ((( effects sampling algorithm ) OR ( effects making algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element novel algorithm") OR ((("effects sampling algorithm") OR ("effects making algorithm"))))*.
