Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
estimation algorithmss » estimation algorithms, estimation algorithm, optimization algorithms
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
cost estimation » pose estimation, risk estimation, cover estimations

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: (( cost estimation algorithmss ) OR ( parameters optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( cost estimation algorithmss ) or ( parameters optimization algorithm ))*.
