Perhaps you should try some spelling variations:
"modified bayesian estimation algorithms" » "modified bayesian estimation algorithm", "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm"
"modified caging approximation algorithms" » "modified one approximation algorithms", "modified time approximation algorithms"

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 caging approximation algorithms") OR ("modified bayesian estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified caging approximation algorithms ) or ( modified bayesian estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging approximation algorithms") or ("modified bayesian estimation algorithms"))*.
