Perhaps you should try some spelling variations:
"pre processing algorithm" » "pre modeling algorithm" (Expand Search), "pre routing algorithm" (Expand Search), "pre tracking algorithm" (Expand Search), "time processing algorithm" (Expand Search), "_ processing algorithm" (Expand Search), "rna processing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent data algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present data algorithm\") OR (((\"pre processing algorithm\") OR (\"element method algorithm\"))))~".
• Removing quotes may allow a broader search: (( present data algorithm ) OR ((( pre processing algorithm ) OR ( element method algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("present data algorithm") OR ((("pre processing algorithm") OR ("element method algorithm"))))*.
