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

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 algorithmss ) OR ( response optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( response estimation algorithmss ) or ( response optimisation algorithm ))*.
