Perhaps you should try some spelling variations:
"based learning algorithm" » "based learning algorithms" (Expand Search)
"data code algorithm" » "data cosine algorithm" (Expand Search), "data rd algorithm" (Expand Search), "data colony algorithm" (Expand Search)
"element mould algorithm" » "elements mould algorithm" (Expand Search), "element could algorithm" (Expand Search), "element would algorithm" (Expand Search), "element mold algorithm" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("element mould algorithm") OR ((("data code algorithm") OR ("based learning algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element mould algorithm\") OR (((\"data code algorithm\") OR (\"based learning algorithm\"))))".
• Removing quotes may allow a broader search: (( element mould algorithm ) OR ((( data code algorithm ) OR ( based learning algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element mould algorithm") OR ((("data code algorithm") OR ("based learning algorithm"))))*.
