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 algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search)
"element cscap algorithm" » "element cc3d algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element custom 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 algorithms") OR ("element cscap algorithm"))) OR ("path learning algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithms\") OR (\"element cscap algorithm\"))) OR (\"path learning algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithms ) OR ( element cscap algorithm ))) OR ( path learning algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithms") OR ("element cscap algorithm"))) OR ("path learning algorithm"))*.
