Perhaps you should try some spelling variations:
optimisation algorithmssssss » optimisation algorithm, optimization algorithms
parameter optimisation » parameter optimization, parameter estimation
attributed estimation » attribute optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm

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: (( parameter optimisation algorithmssssss ) OR ( attributed estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( parameter optimisation algorithmssssss ) or ( attributed estimation algorithms ))*.
