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