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)
"present data algorithms" » "present art algorithms" (Expand Search), "present all algorithms" (Expand Search), "present both algorithms" (Expand Search), "presence data algorithms" (Expand Search), "present day algorithms" (Expand Search), "recent data algorithms" (Expand Search)
"effects using algorithm" » "effects using algorithms" (Expand Search), "effects routing algorithm" (Expand Search), "effects fusion algorithm" (Expand Search), "events 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: (("present data algorithms") OR ((("effects sampling algorithm") OR ("effects using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present data algorithms\") OR (((\"effects sampling algorithm\") OR (\"effects using algorithm\"))))".
• Removing quotes may allow a broader search: (( present data algorithms ) OR ((( effects sampling algorithm ) OR ( effects using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("present data algorithms") OR ((("effects sampling algorithm") OR ("effects using algorithm"))))*.
