Perhaps you should try some spelling variations:
"defined network optimization algorithmss" » "defined network optimisation algorithm", "defined network estimation algorithms", "defined network estimation algorithm", "defined network optimisation algorithms", "defined network estimation algorithmss"
"modified bayesian optimization algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm"

You may be able to get more results by adjusting your search query.

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