Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
bayesian optimisation » bayesian optimization
solutions algorithm » solution algorithm, evolution algorithm, evolutionary algorithm
modified positive » modified passive, modified adaptive

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