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