Perhaps you should try some spelling variations:
"defined network optimization algorithm" » "defined network optimization algorithms", "defined network optimisation algorithm", "defined network estimation algorithm"
"modified adaptive estimation algorithms" » "modified adaptive estimation algorithm", "modified adaptive optimization algorithms", "modified adaptive optimisation algorithm", "modified adaptive ventilation algorithms", "modified quantile estimation algorithms", "modified adaptive quantization algorithms", "modified passive estimation 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 adaptive estimation algorithms") OR ("defined network optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive estimation algorithms\") OR (\"defined network optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithms ) OR ( defined network optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithms") OR ("defined network optimization algorithm"))*.
