Perhaps you should try some spelling variations:
"parameters optimisation algorithmss" » "parameters optimization algorithms", "parameters estimation algorithms", "parameters estimation algorithm", "parameter optimization algorithmss", "parameter estimation algorithmss", "parameters optimization algorithmsss", "parameters estimation algorithmss", "parameters estimation algorithmsss"
"network optimisation algorithm" » "network optimization algorithms", "network estimation algorithm", "network estimation algorithms", "network optimization algorithm"

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: (("network optimisation algorithm") OR ("parameters optimisation algorithmss"))~.
• Removing quotes may allow a broader search: (( network optimisation algorithm ) or ( parameters optimisation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("network optimisation algorithm") or ("parameters optimisation algorithmss"))*.
