Perhaps you should try some spelling variations:
optimisation algorithms » optimization algorithms, estimation algorithms, estimation algorithm
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
cost optimisation » robust optimization, _ optimisation, qoe optimization

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( cost optimisation algorithms ) or ( parameter optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( cost optimisation algorithms ) OR ( parameter optimisation algorithm ))*.
