Perhaps you should try some spelling variations:
"modified parameter optimization algorithmssss" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter optimization algorithmsssss", "modified parameter optimisation algorithmssss", "modified parameter estimation algorithmssss", "modified parameters optimization algorithmssss"
"modified df optimization algorithm" » "modified df optimization algorithms", "modified df optimisation algorithm", "modified df estimation algorithm", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified _ optimisation algorithm", "modified adam optimization algorithm", "modified bi1 optimization 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 optimization algorithm") OR ("modified parameter optimization algorithmssss"))~.
• Removing quotes may allow a broader search: (( modified df optimization algorithm ) or ( modified parameter optimization algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified df optimization algorithm") or ("modified parameter optimization algorithmssss"))*.
