Perhaps you should try some spelling variations:
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"select control algorithm" » "select controls algorithm" (Expand Search), "selected control algorithm" (Expand Search), "self control algorithm" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"select control algorithm\") OR (\"element method algorithm\"))) OR (\"level coding algorithm\"))~".
• Removing quotes may allow a broader search: (((( select control algorithm ) OR ( element method algorithm ))) OR ( level coding algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("select control algorithm") OR ("element method algorithm"))) OR ("level coding algorithm"))*.
