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

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: (( response estimation algorithms ) OR ( response optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( response estimation algorithms ) or ( response optimized algorithms ))*.
