Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithms » optimisation algorithm, estimation algorithm, optimized algorithms
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
response estimation » response optimization, pose estimation, response association

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

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