Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
market optimization » game optimization, parameter optimization, market capitalization
emotion algorithm » evolution algorithm, estimation algorithm, predation algorithm
mapping learning » machine learning, enabling learning
learning emotion » learning method
modified market » modified male

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: (( mapping learning emotion algorithm ) OR ( modified market optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( mapping learning emotion algorithm ) or ( modified market optimization algorithms ))*.
