Perhaps you should try some spelling variations:
"agent learning algorithm" » "agent learning algorithms" (Expand Search), "student learning algorithm" (Expand Search)
"element mining algorithm" » "element means algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "element bonding algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element other algorithms" (Expand Search), "element art algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "elements ree algorithms" (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: (((("agent learning algorithm") OR ("element mining algorithm"))) OR ("element tree algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"agent learning algorithm\") OR (\"element mining algorithm\"))) OR (\"element tree algorithms\"))".
• Removing quotes may allow a broader search: (((( agent learning algorithm ) OR ( element mining algorithm ))) OR ( element tree algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("agent learning algorithm") OR ("element mining algorithm"))) OR ("element tree algorithms"))*.
