Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified notion optimisation algorithms", "modified notion estimation algorithmss", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"defined network optimization algorithm" » "defined network optimisation algorithm", "defined network estimation algorithm", "defined network estimation algorithms", "designed network optimization algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("defined network optimization algorithm") OR ("modified notion optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"defined network optimization algorithm\") OR (\"modified notion optimization algorithms\"))*".
• Removing quotes may allow a broader search: (( defined network optimization algorithm ) OR ( modified notion optimization algorithms ))*.
