Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
optimizer algorithm » optimizer algorithms, optimized algorithm, optimized algorithms
bayesian estimation » bayesian optimization
modified choosing » modified caging

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 choosing optimizer algorithm ) OR ( modified bayesian estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified choosing optimizer algorithm ) or ( modified bayesian estimation algorithms ))*.
