Perhaps you should try some spelling variations:
"modified based optimization algorithms" » "modified based optimisation algorithm", "modified based estimation algorithms", "modified based estimation algorithm", "modified based optimisation algorithms", "modified based estimation algorithmss", "modified game optimization algorithms", "modified market optimization algorithms", "modified qoe optimization algorithms", "modified male optimization algorithms"
"defined network optimization algorithm" » "defined network optimisation algorithm", "defined network estimation algorithm", "defined network estimation algorithms"

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

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