Perhaps you should try some spelling variations:
"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"
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"

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