Perhaps you should try some spelling variations:
"modified stochastic optimisation algorithmss" » "modified stochastic optimisation algorithm", "modified stochastic optimization algorithms", "modified stochastic estimation algorithms", "modified stochastic optimization algorithmss", "modified static optimization algorithmss", "modified stochastic configuration algorithmss"
"modified bayesian optimization algorithm" » "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm", "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 stochastic optimisation algorithmss") OR ("modified bayesian optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified stochastic optimisation algorithmss ) or ( modified bayesian optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimisation algorithmss") or ("modified bayesian optimization algorithm"))*.
