Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
passive optimization » bayesian optimization, game optimization, policy optimization
emotion algorithm » evolution algorithm, estimation algorithm, predation algorithm
modified passive » modified adaptive
learning emotion » learning method
mobile learning » machine learning

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified passive optimization algorithms ) OR ( mobile learning emotion algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive optimization algorithms ) or ( mobile learning emotion algorithm ))*.
