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 estimates algorithms" » "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimized algorithms"

Try widening your search to All Fields.

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