Perhaps you should try some spelling variations:
allocation optimisation » allocation optimization
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
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 algorithms ) OR ( allocation optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( response estimation algorithms ) or ( allocation optimisation algorithm ))*.
