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