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