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"
"modified passive convolution algorithms" » "modified passive evolution algorithm", "modified passive solution algorithm", "modified adaptive convolution 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 optimization algorithms") or ("modified passive convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quantile optimization algorithms") OR ("modified passive convolution algorithms")).
• Removing quotes may allow a broader search: (( modified quantile optimization algorithms ) or ( modified passive convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified quantile optimization algorithms") or ("modified passive convolution algorithms"))*.
