Perhaps you should try some spelling variations:
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization algorithm"
"modified parameter optimized algorithmss" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization algorithmss"

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