Perhaps you should try some spelling variations:
"peer learning algorithm" » "peer learning algorithms" (Expand Search), "deep learning algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"element cscap algorithm" » "element cosine algorithm" (Expand Search), "elements cscap 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 ((("peer learning algorithm") OR ("element cscap algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"peer learning algorithm\") OR (\"element cscap algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( peer learning algorithm ) OR ( element cscap algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("peer learning algorithm") OR ("element cscap algorithm"))))*.
