Perhaps you should try some spelling variations:
"modified notion optimization algorithmssss" » "modified notion optimisation algorithm", "modified notion optimisation algorithmsss", "modified notion estimation algorithmssss", "modified notion estimation algorithmsss", "modified network optimization algorithmssss", "modified policy optimization algorithmssss", "modified allocation optimization algorithmssss"
"modified df optimization algorithms" » "modified df optimisation algorithm", "modified df estimation algorithms", "modified df estimation algorithm", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified _ optimisation algorithms", "modified adam optimization algorithms", "modified bi1 optimization algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified notion optimization algorithmssss") or ("modified df optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion optimization algorithmssss") OR ("modified df optimization algorithms")).
• Removing quotes may allow a broader search: (( modified notion optimization algorithmssss ) or ( modified df optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithmssss") or ("modified df optimization algorithms"))*.
