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 estimation algorithms" » "certified network estimation algorithm", "certified network optimization algorithms", "certified network optimisation algorithm", "verified network estimation algorithms"

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