Perhaps you should try some spelling variations:
"modified bayesian optimisation algorithms" » "modified bayesian optimization algorithms", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm", "modified bayesian optimization algorithmss", "modified bayesian estimation algorithmss"
"modified static optimisation algorithm" » "modified static optimization algorithms", "modified static estimation algorithm", "modified static estimation algorithms", "modified static optimization algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified static optimisation algorithm") or ("modified bayesian optimisation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified static optimisation algorithm") OR ("modified bayesian optimisation algorithms")).
• Removing quotes may allow a broader search: (( modified static optimisation algorithm ) or ( modified bayesian optimisation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimisation algorithm") or ("modified bayesian optimisation algorithms"))*.
