Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
optimizer algorithms » optimized algorithms, optimization algorithms
parameter estimation » parameter estimates, parameter optimization
optimized algorithm » optimized algorithms
same » some

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( same ((optimized algorithm) or (optimizer algorithms)) ) or ( parameter estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( same ((optimized algorithm) OR (optimizer algorithms)) ) OR ( parameter estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( same ((optimized algorithm) or (optimizer algorithms)) ) or ( parameter estimation algorithms ))*.
