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

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 learning convolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithms") OR ("modified learning convolution algorithm"))*.
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithms ) or ( modified learning convolution algorithm ))*.
