Perhaps you should try some spelling variations:
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified network optimizer algorithms\") OR (\"modified objective allocation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified network optimizer algorithms ) OR ( modified objective allocation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network optimizer algorithms") OR ("modified objective allocation algorithms"))*.
