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 algorithms" » "modified network optimized algorithm", "modified network optimizer algorithms", "modified network optimization algorithms", "certified network optimized algorithms", "defined network optimized algorithms", "modified near optimized algorithms"

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 objective optimisation algorithm") OR ("modified network optimized algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) or ( modified network optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") or ("modified network optimized algorithms"))*.
