Perhaps you should try some spelling variations:
"modified caging optimization algorithmss" » "modified caging optimisation algorithm", "modified caging estimation algorithms", "modified caging estimation algorithm", "modified caging optimisation algorithms", "modified caging estimation algorithmss", "modified staffing optimization algorithmss"
"modified bayesian optimization algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation 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 optimization algorithms") or ("modified caging optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithms") OR ("modified caging optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithms ) or ( modified caging optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimization algorithms") or ("modified caging optimization algorithmss"))*.
