Perhaps you should try some spelling variations:
"modified bi1 optimization algorithms" » "modified bi1 optimisation algorithm", "modified bi1 estimation algorithms", "modified bi1 estimation algorithm", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified game optimization algorithms"
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive quantization algorithm\") OR (\"modified bi1 optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) OR ( modified bi1 optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithm") OR ("modified bi1 optimization algorithms"))*.
