Perhaps you should try some spelling variations:
"modified quantile optimization algorithms" » "modified quantile optimisation algorithm", "modified quantile estimation algorithms", "modified quantile optimized algorithms", "modified quadratic optimization algorithms", "modified static optimization algorithms", "modified adaptive optimization algorithms"
"modified adam estimation algorithm" » "modified df estimation algorithm", "modified near 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 adam estimation algorithm") OR ("modified quantile optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified adam estimation algorithm ) or ( modified quantile optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam estimation algorithm") or ("modified quantile optimization algorithms"))*.
