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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified risk optimisation algorithms\") OR (\"modified bayesian optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified risk optimisation algorithms ) OR ( modified bayesian optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified risk optimisation algorithms") OR ("modified bayesian optimization algorithm"))*.
