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