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"
"modified caging convolution algorithm" » "modified caging convolution algorithms", "modified caging evolution algorithm", "modified caging solution algorithm", "modified learning convolution algorithm"

Try widening your search to All Fields.

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 optimisation algorithm") or ("modified caging convolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimisation algorithm") OR ("modified caging convolution algorithm")).
• Removing quotes may allow a broader search: (( modified bayesian optimisation algorithm ) or ( modified caging convolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimisation algorithm") or ("modified caging convolution algorithm"))*.
