Perhaps you should try some spelling variations:
"element content algorithm" » "element control algorithm" (Expand Search), "element colony algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements content algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"data finding algorithm" » "data mining algorithm" (Expand Search), "data hiding 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: (("data finding algorithm") OR ((("element method algorithm") OR ("element content algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data finding algorithm\") OR (((\"element method algorithm\") OR (\"element content algorithm\"))))".
• Removing quotes may allow a broader search: (( data finding algorithm ) OR ((( element method algorithm ) OR ( element content algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data finding algorithm") OR ((("element method algorithm") OR ("element content algorithm"))))*.
