Perhaps you should try some spelling variations:
optimisation algorithmss » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective optimization » multiobjective optimization
bayesian optimisation » bayesian optimization

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified objective optimization algorithms ) OR ( modified bayesian optimisation algorithmss ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimization algorithms ) OR ( modified bayesian optimisation algorithmss ))*.
