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