Perhaps you should try some spelling variations:
"stool processing algorithm" » "stool modeling algorithm" (Expand Search), "stool routing algorithm" (Expand Search), "stool tracking algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "food processing algorithm" (Expand Search), "signal processing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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 method algorithm") OR ((("stool processing algorithm") OR ("relevant data algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"stool processing algorithm\") OR (\"relevant data algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( stool processing algorithm ) OR ( relevant data algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("stool processing algorithm") OR ("relevant data algorithm"))))*.
