Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
modified learning » mobile learning, modified caging
emotion algorithm » evolution algorithm, estimation algorithm, predation algorithm
learning emotion » learning method

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 learning emotion algorithm ) OR ( modified parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified learning emotion algorithm ) or ( modified parameter optimisation algorithm ))*.
