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