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