Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified network optimization algorithms" » "modified network optimisation algorithm", "modified network estimation algorithms", "modified network estimation algorithm", "certified network optimization algorithms", "defined network optimization algorithms", "modified near optimization 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: (("modified network optimization algorithms") or ("modified multiobjective optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimization algorithms") OR ("modified multiobjective optimized algorithms")).
• Removing quotes may allow a broader search: (( modified network optimization algorithms ) or ( modified multiobjective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithms") or ("modified multiobjective optimized algorithms"))*.
