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