Perhaps you should try some spelling variations:
"modified via convolution algorithms" » "modified via evolution algorithm", "modified via solution algorithm", "modified bi1 convolution algorithms", "modified adam convolution algorithms", "modified near convolution algorithms"
"modified dfdaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive estimation 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 dfdaptive estimation algorithm") OR ("modified via convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified dfdaptive estimation algorithm ) or ( modified via convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified dfdaptive estimation algorithm") or ("modified via convolution algorithms"))*.
