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 models algorithm" » "effects modeling algorithm" (Expand Search), "effects modbo algorithm" (Expand Search), "effects forest algorithm" (Expand Search), "effects model algorithm" (Expand Search)
"effects novel algorithm" » "effects forest algorithm" (Expand Search), "effects model algorithm" (Expand Search), "effects panel algorithm" (Expand Search), "offers novel 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 models algorithm") OR ("effects novel algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element learning algorithm\") OR (((\"effects models algorithm\") OR (\"effects novel algorithm\"))))".
• Removing quotes may allow a broader search: (( element learning algorithm ) OR ((( effects models algorithm ) OR ( effects novel algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element learning algorithm") OR ((("effects models algorithm") OR ("effects novel algorithm"))))*.
