Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
parameter estimates » parameter estimation
estimates algorithm » estimation algorithm, estimation algorithms
code parameter » one parameter, common parameter

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code parameter estimates algorithm ) or ( modified parameters optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code parameter estimates algorithm ) OR ( modified parameters optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( code parameter estimates algorithm ) or ( modified parameters optimization algorithm ))*.
