Perhaps you should try some spelling variations:
"modified network estimation algorithms" » "modified network estimation algorithm", "modified network optimization algorithms", "modified network optimisation algorithm", "certified network estimation algorithms", "defined network estimation algorithms", "modified near estimation algorithms"
"modified bayesian optimized algorithm" » "modified bayesian optimized algorithms", "modified bayesian optimizer algorithms", "modified bayesian optimization 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 optimized algorithm") OR ("modified network estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified bayesian optimized algorithm ) or ( modified network estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimized algorithm") or ("modified network estimation algorithms"))*.
