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