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

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 ( risk optimization algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( robust estimation algorithms ) OR ( risk optimization algorithms ))*.
