Perhaps you should try some spelling variations:
"path learning algorithm" » "path learning algorithms" (Expand Search), "rate learning algorithm" (Expand Search), "graph learning algorithm" (Expand Search), "a learning algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"elements cscap algorithm" » "elements cc3d algorithm" (Expand Search), "elements ipca algorithm" (Expand Search), "elements custom algorithm" (Expand Search), "elements crcy 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: (("path learning algorithm") OR ((("element method algorithm") OR ("elements cscap algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"path learning algorithm\") OR (((\"element method algorithm\") OR (\"elements cscap algorithm\"))))".
• Removing quotes may allow a broader search: (( path learning algorithm ) OR ((( element method algorithm ) OR ( elements cscap algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("path learning algorithm") OR ((("element method algorithm") OR ("elements cscap algorithm"))))*.
