Perhaps you should try some spelling variations:
"argument mapping algorithm" » "argument making algorithm" (Expand Search), "argument mining algorithm" (Expand Search), "argument learning 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)
"elements box algorithm" » "elements best algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements b algorithm" (Expand Search), "elements upon 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: (("elements box algorithm") OR ((("argument mapping algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements box algorithm\") OR (((\"argument mapping algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements box algorithm ) OR ((( argument mapping algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements box algorithm") OR ((("argument mapping algorithm") OR ("level coding algorithm"))))*.
