Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation 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.

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