Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
bayesian optimisation » bayesian optimization
optimized algorithm » optimized algorithms, optimizer algorithms
modified made » modified male, modified adam, modified df

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 made optimized algorithm ) OR ( modified bayesian optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified made optimized algorithm ) or ( modified bayesian optimisation algorithm ))*.
