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