Perhaps you should try some spelling variations:
"implement mining algorithm" » "implement finding algorithm" (Expand Search), "implement making algorithm" (Expand Search), "implement training algorithms" (Expand Search), "implemented mining algorithm" (Expand Search), "implementing mining algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithm" (Expand Search), "element ree 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: (("implement mining algorithm") OR ((("element rf algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement mining algorithm\") OR (((\"element rf algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( implement mining algorithm ) OR ((( element rf algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement mining algorithm") OR ((("element rf algorithm") OR ("element method algorithm"))))*.
