Perhaps you should try some spelling variations:
"modified notion optimisation algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms"
"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"

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