Perhaps you should try some spelling variations:
optimisation algorithmssss » optimization algorithms
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
post optimisation » robust optimization, _ optimisation, qoe 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: (( parameter optimisation algorithm ) OR ( post optimisation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (( parameter optimisation algorithm ) or ( post optimisation algorithmssss ))*.
