Perhaps you should try some spelling variations:
parameters estimation » parameter estimation, parameter estimates, parameter optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
learning evolution » learning convolution, learning emotion
coarse learning » coarse graining

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: (( coarse learning evolution algorithm ) OR ( modified parameters estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( coarse learning evolution algorithm ) or ( modified parameters estimation algorithms ))*.
