Perhaps you should try some spelling variations:
"modified dfdaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive estimation algorithm", "modified _daptive estimation algorithm", "modified adamdaptive estimation algorithm", "modified bi1daptive estimation algorithm"
"modified df optimized algorithm" » "modified df optimized algorithms", "modified df optimizer algorithms", "modified _ optimized algorithm", "modified _ optimize algorithm", "modified adam optimized algorithm", "modified bi1 optimized 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 df optimized algorithm"))~.
• Removing quotes may allow a broader search: (( modified dfdaptive estimation algorithm ) or ( modified df optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified dfdaptive estimation algorithm") or ("modified df optimized algorithm"))*.
