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