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