Perhaps you should try some spelling variations:
"modified quantile optimisation algorithm" » "modified quantile optimization algorithms", "modified quantile estimation algorithm", "modified adaptive optimisation algorithm"
"modified adam estimation algorithms" » "modified adam estimation algorithm", "modified adam optimization algorithms", "modified adam approximation algorithms", "modified df estimation algorithms", "modified near estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified quantile optimisation algorithm") OR ("modified adam estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified quantile optimisation algorithm\") OR (\"modified adam estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified quantile optimisation algorithm ) OR ( modified adam estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified quantile optimisation algorithm") OR ("modified adam estimation algorithms"))*.
