Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithm", "modified adaptive optimized algorithms", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"
"modified quantile estimation algorithms" » "modified quantile estimation algorithm", "modified quantile optimisation algorithm", "modified quantile approximation algorithms"

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 quantile estimation algorithms") OR ("modified adaptive optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified quantile estimation algorithms ) or ( modified adaptive optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified quantile estimation algorithms") or ("modified adaptive optimization algorithms"))*.
