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", "designed network optimisation algorithm"
"modified response optimization algorithm" » "modified response optimization algorithms", "modified response estimation algorithm", "modified response estimation algorithms"

Try widening your search to All Fields.

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 optimisation algorithm") or ("modified response optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("defined network optimisation algorithm") OR ("modified response optimization algorithm")).
• Removing quotes may allow a broader search: (( defined network optimisation algorithm ) or ( modified response optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("defined network optimisation algorithm") or ("modified response optimization algorithm"))*.
