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

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 bayesian optimization algorithms") OR ("modified objective optimisation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithms ) or ( modified objective optimisation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimization algorithms") or ("modified objective optimisation algorithmss"))*.
