Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"designed network optimized algorithm" » "designed network optimized algorithms", "designed network optimizer algorithms", "designed network optimization algorithm", "defined network optimized algorithm"

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