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