Perhaps you should try some spelling variations:
"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"
"modified attribute optimization algorithm" » "modified attribute optimization algorithms", "modified attribute optimisation algorithm", "modified attribute estimation algorithm", "modified attributed optimization algorithm", "modified attributes 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 attribute optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified df optimization algorithm ) or ( modified attribute optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified df optimization algorithm") or ("modified attribute optimization algorithm"))*.
