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