Perhaps you should try some spelling variations:
"modified risk optimization algorithms" » "modified risk optimisation algorithm", "modified risk estimation algorithms", "modified risk estimation algorithm", "modified risk optimisation algorithms", "modified risk estimation algorithmss", "modified robust optimization algorithms", "modified _ optimization algorithms", "modified game optimization algorithms", "modified bi1 optimization algorithms"
"modified bayesian optimization algorithm" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithm", "modified bayesian estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified risk optimization algorithms") or ("modified bayesian optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified risk optimization algorithms") OR ("modified bayesian optimization algorithm")).
• Removing quotes may allow a broader search: (( modified risk optimization algorithms ) or ( modified bayesian optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified risk optimization algorithms") or ("modified bayesian optimization algorithm"))*.
