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