Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
estimation algorithmss » estimation algorithms, estimation algorithm, optimization algorithms
same estimation » pose estimation, sphere estimation

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