Perhaps you should try some spelling variations:
"defined network optimization algorithm" » "defined network optimization algorithms", "defined network optimisation algorithm", "defined network estimation algorithm", "designed network optimization algorithm"
"modified adam optimized algorithms" » "modified adam optimized algorithm", "modified adam optimizer algorithms", "modified adam optimization algorithms", "modified df optimized algorithms", "modified near optimized algorithms"

You may be able to get more results by adjusting your search query.

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