Perhaps you should try some spelling variations:
"modified quantile estimation algorithms" » "modified quantile estimation algorithm", "modified quantile optimization algorithms", "modified quantile optimisation algorithm", "modified adaptive estimation algorithms"
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion 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: "((\"modified learning method algorithm\") OR (\"modified quantile estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified learning method algorithm ) OR ( modified quantile estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning method algorithm") OR ("modified quantile estimation algorithms"))*.
