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 male evolution algorithm" » "modified male solution algorithm", "modified male evolutionary algorithm", "modified male convolution algorithms", "modified sales evolution algorithm", "modified early evolution algorithm", "modified time evolution algorithm"

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