Perhaps you should try some spelling variations:
"defined network optimisation algorithm" » "defined network optimization algorithms", "defined network estimation algorithms", "defined network optimization algorithm"
"modified adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization algorithm", "modified passive estimation 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 estimation algorithm\") OR (\"defined network optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithm ) OR ( defined network optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithm") OR ("defined network optimisation algorithm"))*.
