Perhaps you should try some spelling variations:
"defined network optimization algorithms" » "defined network optimisation algorithm", "defined network estimation algorithms", "defined network estimation algorithm", "designed network optimization algorithms"
"modified caging optimized algorithm" » "modified caging optimized algorithms", "modified caging optimizer algorithms", "modified aging optimized algorithm", "modified changing optimized algorithm", "modified charging optimized algorithm"

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