Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
estimates algorithms » estimation algorithm, optimized algorithms, optimizer algorithms
parameter estimates » parameter estimation
poses estimation » pose estimation, pulses 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: (( poses estimation algorithms ) OR ( parameter estimates algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( poses estimation algorithms ) or ( parameter estimates algorithms ))*.
