Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
write estimation » risk estimation, pose estimation

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( write estimation algorithms ) OR ( parameter optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( write estimation algorithms ) OR ( parameter optimisation algorithm ))*".
