Perhaps you should try some spelling variations:
"element learning algorithm" » "element learning algorithms" (Expand Search), "excellent learning algorithm" (Expand Search), "student learning algorithm" (Expand Search), "agent learning algorithm" (Expand Search)
"effects mining algorithm" » "effects means algorithm" (Expand Search), "effects arising algorithm" (Expand Search), "effects main algorithm" (Expand Search), "effects modeling algorithm" (Expand Search)
"effects using algorithm" » "effects routing algorithm" (Expand Search), "effects fusion algorithm" (Expand Search), "effects cosine algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("element learning algorithm") OR ((("effects using algorithm") OR ("effects mining algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element learning algorithm\") OR (((\"effects using algorithm\") OR (\"effects mining algorithm\"))))".
• Removing quotes may allow a broader search: (( element learning algorithm ) OR ((( effects using algorithm ) OR ( effects mining algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element learning algorithm") OR ((("effects using algorithm") OR ("effects mining algorithm"))))*.
