Perhaps you should try some spelling variations:
"modified risk optimization algorithmss" » "modified risk optimization algorithms", "modified risk estimation algorithms", "modified risk estimation algorithm", "modified robust optimization algorithmss", "modified _ optimization algorithmss", "modified game optimization algorithmss", "modified bi1 optimization algorithmss"
"modified bayesian optimisation algorithm" » "modified bayesian optimization algorithms", "modified bayesian estimation algorithm", "modified bayesian estimation algorithms", "modified bayesian optimization 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 risk optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimisation algorithm") OR ("modified risk optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified bayesian optimisation algorithm ) or ( modified risk optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimisation algorithm") or ("modified risk optimization algorithmss"))*.
