Perhaps you should try some spelling variations:
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
estimates algorithms » estimation algorithms, estimation algorithm, optimizer algorithms
parameter estimates » parameter estimation
charging optimized » choosing optimizer
modified charging » modified caging, modified carbon

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 parameter estimates algorithms ) OR ( modified charging optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified parameter estimates algorithms ) or ( modified charging optimized algorithms ))*.
