Perhaps you should try some spelling variations:
"modified bayesian optimization algorithm" » "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm", "modified bayesian estimation algorithm"
"modified parameter estimation algorithmss" » "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimates algorithmss", "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 bayesian optimization algorithm") or ("modified parameter estimation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithm") OR ("modified parameter estimation algorithmss"))*.
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithm ) or ( modified parameter estimation algorithmss ))*.
