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