Perhaps you should try some spelling variations:
"effects sampling algorithm" » "effects mining algorithm" (Expand Search), "effects modeling algorithm" (Expand Search), "effects arising 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)
"effects along algorithm" » "effects colony algorithm" (Expand Search), "effects making algorithm" (Expand Search), "effects adonis algorithm" (Expand Search), "effects using 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 along algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element novel algorithm\") OR (((\"effects sampling algorithm\") OR (\"effects along algorithm\"))))".
• Removing quotes may allow a broader search: (( element novel algorithm ) OR ((( effects sampling algorithm ) OR ( effects along algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element novel algorithm") OR ((("effects sampling algorithm") OR ("effects along algorithm"))))*.
