Perhaps you should try some spelling variations:
"argument learning algorithm" » "argument learning algorithms" (Expand Search), "agent learning algorithm" (Expand Search), "student learning algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (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)

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

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