Perhaps you should try some spelling variations:
"modified via optimization algorithms" » "modified via optimisation algorithm", "modified via estimation algorithms", "modified via estimation algorithm", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified stage optimization algorithms", "modified bi1 optimization algorithms", "modified adam optimization algorithms", "modified near optimization algorithms"
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization 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 adaptive quantization algorithm") or ("modified via optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive quantization algorithm") OR ("modified via optimization algorithms")).
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) or ( modified via optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithm") or ("modified via optimization algorithms"))*.
