Perhaps you should try some spelling variations:
"modified bayesian optimization algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm"
"modified parameter optimized algorithmss" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization algorithmss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameter optimized algorithmss") OR ("modified bayesian optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameter optimized algorithmss\") OR (\"modified bayesian optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified parameter optimized algorithmss ) OR ( modified bayesian optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimized algorithmss") OR ("modified bayesian optimization algorithms"))*.
