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