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

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: "(( machines learning method algorithm ) OR ( modified network optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( machines learning method algorithm ) OR ( modified network optimization algorithm ))*.
