Perhaps you should try some spelling variations:
"modified df simulation algorithm" » "modified df solution algorithm", "modified df optimisation algorithm", "modified df estimation algorithms", "modified _ simulation algorithm", "modified a simulation algorithm", "modified 3d simulation algorithm", "modified adam simulation algorithm", "modified bi1 simulation algorithm"
"modified dfdamdamdaptive estimation algorithm" » "modified _damdamdaptive estimation algorithm", "modified adamdamdamdaptive estimation algorithm", "modified bi1damdamdaptive 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 df simulation algorithm") OR ("modified dfdamdamdaptive estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified df simulation algorithm ) or ( modified dfdamdamdaptive estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified df simulation algorithm") or ("modified dfdamdamdaptive estimation algorithm"))*.
