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

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: (( parameters estimation algorithms ) OR ( attribute optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( parameters estimation algorithms ) or ( attribute optimized algorithms ))*.
