Perhaps you should try some spelling variations:
estimation algorithmss » estimation algorithms, estimation algorithm, optimization algorithms
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
robust optimisation » robust optimization
pulsed estimation » pulses estimation, pose estimation

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( pulsed estimation algorithmss ) or ( robust optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( pulsed estimation algorithmss ) OR ( robust optimisation algorithm ))*.
