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 convolution algorithm" » "mobile learning convolution algorithms", "mobile learning evolution algorithm", "mobile learning solution algorithm", "machine learning convolution 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 convolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified quantile optimization algorithms ) or ( mobile learning convolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified quantile optimization algorithms") or ("mobile learning convolution algorithm"))*.
