Perhaps you should try some spelling variations:
"element making algorithm" » "element learning algorithm" (Expand Search), "element finding algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling 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)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh algorithm" (Expand Search)

Try widening your search to All Fields.

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

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