Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
parameter estimates » parameter estimation
estimates algorithm » estimation algorithm, estimation algorithms
code parameter » one parameter, common parameter

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