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"
"machine learning methods algorithm" » "machine nursing methods algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machine learning methods algorithm\") OR (\"modified quantile optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( machine learning methods algorithm ) OR ( modified quantile optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("machine learning methods algorithm") OR ("modified quantile optimization algorithms"))*.
