Perhaps you should try some spelling variations:
"modified bayesian optimization algorithm" » "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm", "modified bayesian estimation algorithm"
"modified caging convolution algorithm" » "modified caging convolution algorithms", "modified caging evolution algorithm", "modified caging solution algorithm", "modified learning 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 caging convolution algorithm") or ("modified bayesian optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified caging convolution algorithm") OR ("modified bayesian optimization algorithm"))*.
• Removing quotes may allow a broader search: (( modified caging convolution algorithm ) or ( modified bayesian optimization algorithm ))*.
