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