Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive optimisation algorithms", "modified adaptive estimation algorithmss", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"
"modified df optimization algorithm" » "modified df optimisation algorithm", "modified df estimation algorithm", "modified df estimation algorithms", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified _ optimisation algorithm", "modified adam optimization algorithm", "modified bi1 optimization algorithm"

Try widening your search to All Fields.

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

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