Perhaps you should try some spelling variations:
evolutionary algorithm » evolution algorithm, solution algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
parameter estimation » parameter estimates, parameter optimization
when learning » deep learning, how learning, shot 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: (( when learning evolutionary algorithm ) OR ( modified parameter estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( when learning evolutionary algorithm ) or ( modified parameter estimation algorithms ))*.
