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)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"data learning algorithms" » "meta learning algorithms" (Expand Search), "deep learning algorithms" (Expand Search), "a learning algorithms" (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: (("elements method algorithm") OR ((("data encoding algorithm") OR ("data learning algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data encoding algorithm\") OR (\"data learning algorithms\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data encoding algorithm ) OR ( data learning algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data encoding algorithm") OR ("data learning algorithms"))))*.
