Perhaps you should try some spelling variations:
"data encoding algorithm" » "data finding algorithm" (Expand Search), "data cosine algorithm" (Expand Search), "data including algorithm" (Expand Search), "data according algorithm" (Expand Search), "data recording algorithm" (Expand Search)
"based machine algorithm" » "based matching algorithm" (Expand Search), "based matching algorithms" (Expand Search), "based making 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)

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