Perhaps you should try some spelling variations:
"element controls algorithm" » "element control algorithm" (Expand Search), "elements controls algorithm" (Expand Search)
"element making algorithm" » "element cosine algorithm" (Expand Search), "elements making algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level colony algorithm" (Expand Search), "level scheduling 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 controls algorithm") OR ((("element making algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element controls algorithm\") OR (((\"element making algorithm\") OR (\"level coding algorithm\"))))*".
• Removing quotes may allow a broader search: (( element controls algorithm ) OR ((( element making algorithm ) OR ( level coding algorithm ))))*.
