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"
"mobile learning method algorithm" » "mobile learning mom algorithm", "machine learning method algorithm", "mobile learning methods algorithm", "mobile graining methods algorithm", "mobile learning emotion algorithm"

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 optimization algorithms") OR ("mobile learning method algorithm"))~.
• Removing quotes may allow a broader search: (( modified quantile optimization algorithms ) or ( mobile learning method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified quantile optimization algorithms") or ("mobile learning method algorithm"))*.
