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