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

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

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