Perhaps you should try some spelling variations:
"modified network optimisation algorithmss" » "modified network optimisation algorithm", "modified network optimization algorithms", "modified network estimation algorithm", "modified network optimization algorithmss", "certified network optimisation algorithmss", "defined network optimisation algorithmss", "modified near optimisation algorithmss"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation 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 optimisation algorithmss\") OR (\"modified objective estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified network optimisation algorithmss ) OR ( modified objective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network optimisation algorithmss") OR ("modified objective estimation algorithms"))*.
