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), "elements method algorithm" (Expand Search)
"argument making algorithm" » "argument learning algorithm" (Expand Search), "argument finding algorithm" (Expand Search), "argument means algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"data modeling algorithm" » "data modelling algorithm" (Expand Search), "data models 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 method algorithm") OR ("argument making algorithm"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"argument making algorithm\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( argument making algorithm ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("argument making algorithm"))) OR ("data modeling algorithm"))*.
