Perhaps you should try some spelling variations:
"network optimization algorithmssssss" » "network optimization algorithms", "network optimisation algorithm", "network optimization algorithmsssssss", "network optimisation algorithmssssss", "network estimation algorithmssssss"
"parameters optimization algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameters optimization algorithms", "parameters optimisation algorithm", "parameters estimation 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: "((\"network optimization algorithmssssss\") OR (\"parameters optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( network optimization algorithmssssss ) OR ( parameters optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("network optimization algorithmssssss") OR ("parameters optimization algorithm"))*.
