Perhaps you should try some spelling variations:
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation algorithm"
"modified objective optimizer algorithms" » "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimization algorithms", "modified objective optimal 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 network optimisation algorithm") or ("modified objective optimizer algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimisation algorithm") OR ("modified objective optimizer algorithms")).
• Removing quotes may allow a broader search: (( modified network optimisation algorithm ) or ( modified objective optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimisation algorithm") or ("modified objective optimizer algorithms"))*.
