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