Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"certified network optimization algorithm" » "certified network optimization algorithms", "certified network optimisation algorithm", "certified network estimation algorithm", "verified network 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: (("certified network optimization algorithm") OR ("modified multiobjective optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"certified network optimization algorithm\") OR (\"modified multiobjective optimized algorithm\"))".
• Removing quotes may allow a broader search: (( certified network optimization algorithm ) OR ( modified multiobjective optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("certified network optimization algorithm") OR ("modified multiobjective optimized algorithm"))*.
