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