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

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( parameters optimisation algorithm ) OR ( parameter estimation algorithmss ))~".
• Adding a wildcard symbol may retrieve word variants: (( parameters optimisation algorithm ) OR ( parameter estimation algorithmss ))*.
