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