Perhaps you should try some spelling variations:
"modified quantile optimization algorithms" » "modified quantile optimisation algorithm", "modified quantile estimation algorithms", "modified quantile estimation algorithm", "modified quadratic optimization algorithms", "modified static optimization algorithms", "modified adaptive optimization algorithms"
"modified one approximation algorithm" » "modified one approximation algorithms", "modified time approximation algorithm", "modified _ approximation algorithm", "modified rough approximations algorithm", "modified male approximation algorithm", "modified near approximation algorithm", "modified orca approximation 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 one approximation algorithm") OR ("modified quantile optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified one approximation algorithm ) or ( modified quantile optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified one approximation algorithm") or ("modified quantile optimization algorithms"))*.
