Perhaps you should try some spelling variations:
"modified bayesian optimization algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm"
"modified caging convolution algorithms" » "modified caging evolution algorithm", "modified caging solution algorithm", "modified learning convolution algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified bayesian optimization algorithms") or ("modified caging convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithms") OR ("modified caging convolution algorithms"))*.
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithms ) or ( modified caging convolution algorithms ))*.
