Perhaps you should try some spelling variations:
optimization algorithmssssssss » optimization algorithms
parameters estimation » parameter estimation, parameter estimates, parameter optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
market optimization » game optimization, parameter optimization, market capitalization

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( market optimization algorithmssssssss ) OR ( parameters estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( market optimization algorithmssssssss ) or ( parameters estimation algorithms ))*.
