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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithms\") OR (\"modified network optimized algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) OR ( modified network optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") OR ("modified network optimized algorithm"))*.
