Perhaps you should try some spelling variations:
"defined network optimization algorithms" » "defined network optimisation algorithm", "defined network estimation algorithms", "defined network estimation algorithm", "defined network optimisation algorithms", "defined network estimation algorithmss"
"modified adam optimization algorithm" » "modified adam optimisation algorithm", "modified adam estimation algorithm", "modified adam estimation algorithms", "modified game optimization algorithm", "modified stage optimization algorithm", "modified _ optimization algorithm", "modified df optimization algorithm", "modified near optimization algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adam optimization algorithm") OR ("defined network optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adam optimization algorithm\") OR (\"defined network optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified adam optimization algorithm ) OR ( defined network optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adam optimization algorithm") OR ("defined network optimization algorithms"))*.
