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 _ optimize algorithms" » "modified _ optimized algorithms", "modified _ optimizer algorithms", "modified _ optimized 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 _ optimize algorithms\") OR (\"modified network optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified _ optimize algorithms ) OR ( modified network optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified _ optimize algorithms") OR ("modified network optimisation algorithm"))*.
