Perhaps you should try some spelling variations:
estimation algorithmssssss » estimation algorithms, estimation algorithm
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
parameter estimation » parameter estimates, parameter optimization
pulse optimization » policy optimization, game optimization, qoe 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: (( pulse optimization algorithms ) OR ( parameter estimation algorithmssssss ))~.
• Adding a wildcard symbol may retrieve word variants: (( pulse optimization algorithms ) or ( parameter estimation algorithmssssss ))*.
