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