Perhaps you should try some spelling variations:
estimation algorithmss » estimation algorithm, optimization algorithms
parameters estimation » parameter estimation, parameter estimates, parameter optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
topology estimation » topology 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 estimation algorithms ) OR ( topology estimation algorithmss ))~".
• Adding a wildcard symbol may retrieve word variants: (( parameters estimation algorithms ) OR ( topology estimation algorithmss ))*.
