Perhaps you should try some spelling variations:
estimation algorithmss » estimation algorithms, estimation algorithm, optimization algorithms
estimates algorithms » estimation algorithms, estimation algorithm, optimized algorithms
parameter estimates » parameter estimation
topology estimation » topology optimization

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

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