Perhaps you should try some spelling variations:
"verified network optimisation algorithm" » "verified network optimization algorithms", "verified network estimation algorithm", "verified network estimation algorithms", "verified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm"
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("verified network optimisation algorithm") OR ("modified objective allocation algorithms"))~.
• Removing quotes may allow a broader search: (( verified network optimisation algorithm ) or ( modified objective allocation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("verified network optimisation algorithm") or ("modified objective allocation algorithms"))*.
