Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
parameters optimization » parameter optimization, parameter estimation
optimization algorithms » estimation algorithms, estimation algorithm, optimized algorithms
optimisation algorithm » estimation algorithm, estimation algorithms

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

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