Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
robust estimation » robust optimization, pose estimation, risk estimation
same optimisation » game optimization, stage optimization, _ optimisation

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( robust estimation algorithms ) OR ( same optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( robust estimation algorithms ) OR ( same optimisation algorithm ))*.
