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