Perhaps you should try some spelling variations:
"modified df estimation algorithms" » "modified df estimation algorithm", "modified df optimization algorithms", "modified df optimisation algorithm", "modified _ estimation algorithms", "modified adam estimation algorithms", "modified bi1 estimation algorithms"
"modified passive solution algorithm" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive evolutionary algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm", "modified saline solution 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 passive solution algorithm") OR ("modified df estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified passive solution algorithm ) or ( modified df estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive solution algorithm") or ("modified df estimation algorithms"))*.
