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

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 optimization algorithmss") or ("modified bayesian optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimization algorithmss") OR ("modified bayesian optimization algorithm"))*.
• Removing quotes may allow a broader search: (( modified parameter optimization algorithmss ) or ( modified bayesian optimization algorithm ))*.
