Perhaps you should try some spelling variations:
"modified bayesian optimisation algorithm" » "modified bayesian optimization algorithms", "modified bayesian estimation algorithm", "modified bayesian estimation algorithms", "modified bayesian optimization algorithm"
"modified risk optimized algorithms" » "modified risk optimized algorithm", "modified risk optimizer algorithms", "modified risk optimization algorithms", "modified write optimized algorithms", "modified bi1 optimized 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 optimized algorithms") OR ("modified bayesian optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified risk optimized algorithms\") OR (\"modified bayesian optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified risk optimized algorithms ) OR ( modified bayesian optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified risk optimized algorithms") OR ("modified bayesian optimisation algorithm"))*.
