Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
network optimisation » network optimization
method algorithm » mom algorithm
active learning » machine learning
learning method » learning methods, graining methods, learning emotion
certified » verified

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( active learning method algorithm ) OR ( certified network optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( active learning method algorithm ) OR ( certified network optimisation algorithm ))*.
