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