Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithm, optimized algorithms
parameters optimization » parameter optimization, parameter estimation
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
risk estimation » pose estimation
modified risk » modified bi1

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: (( modified risk estimation algorithms ) OR ( modified parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified risk estimation algorithms ) or ( modified parameters optimization algorithms ))*.
