Perhaps you should try some spelling variations:
"modified stochastic approximation algorithms" » "modified diophantine approximation algorithms", "modified stochastic optimization algorithms"
"modified bayesian optimization algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm"

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