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