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