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